Reddit mentions: The best screw & bolt assortment sets

It honestly depends on your budget, how much are you willing to spend?

Here is a great list of prep and upgrades you can do to bring success to your prints:

-Get Vibration Dampners: I can not express how much joy these things have brought many users. The make your machine quiet and greatly decrease ringing in your prints since they ABSORB the vibration coming from your stepper motors. You really only need Two of these for the X and Y axis however you can get another two for the Z-axis drives if you plan on doing a lot of z-hopping.

-BUY FILAMENT IN ADVANCE: get some PLA/ABS/PETG or whatever you want to try printing with. The filament you get with the printer for the most part is garbage HOWEVER I recommend dialing in those settings first then throwing on some nice filament, it'll feel soooo nice. Some commonly accepted/appreciated brands are: eSun PLA+, Hatchbox, Solutech and more

-Get a PEI sheet: Seems like you mentioned this in your post but PEI sheets eliminate the use of gluesticks/tape/hairspray and provide excelent adhesion while making it easy to remove the part after it's cool. This things like to be hot though so increase your bed temp a little at first

-Buy New Fans: The stock hotend/power unit fans are Loud, Noisy and Inefficient. I recommend getting 1 new conrol box fan, 1 new hot end fan and 1 new part blower fan.
You will need 1 40mm fan, 1 50mm fan and a Blower fan or another 40/50mm fan depending on if you print a new hot end mount like a fang.

-Tighten every screw on the printer: You would be surprised how many screws initially are lose either from prior testing or such. Also make sure to test your belt tensions on your printer whne you get it. You want everything tight BUT NOT TOO TIGHT. Give it a snug fit then let it be. Also make sure your belts are 'pluckable' like a guitar string but not tought

-Get some bearings: You may want to get a few ball bearings for when you print out a new filament holder, the stock filament holder is terrible

-Buy some fasteners: M3 bolts and nuts are commonly used on the CR-10S having spares or additional fasteners for adding on parts/printed components to your printer is awesome to have on hand

-Replace the Hotend: This can get a bit frustrating but it can be worth it. If you want you can replace the hotend with something like a volcano or an all metal hot end to print at higher temperatures. With this you can also add on autoleveling if you have the correct mount printed

-Octoprint: I am not very familiar with octoprint since I don't use it myself however I know it can run on a CR-10S. If you want look into how to install octoprint on stock firmware, I know it's pretty easy to use a raspberrypi to remote into your printer as well using octoprint.

-Squash Feet: Replacing your stock machine 'feet' with squash balls or squishy gold balls can also help absorb vibrations from your machine to your table or where it is located. This helps a bit with part quality but it's mostly to reduce the noise carried through your furniture.

-Solder on connectors: If you want you can get some pin connectors to make your fans/electronics easy to switch out depending on your material you are printing, maybe you need a strong part fan or maybe you need a weaker one. It is easy to swap out if it's using a 4pin connector.

-Make an Enclosure: What could be nicer for your printer than a stable environment. Making an enclosure for your printer can help if you live in a rough climate area or if you want to reduce the noise as well.

-Get some Handtools: I'm not sure if you have any or not but some great tools to have are a screwdriver, hexwrenches and a soldering iron depending on how much work you want to be doing on your printer.

For convenience I've added some of the parts mentioned via an Amazon link for prices. I'm not saying buy these things exactly they are just a starting point for reference:

Hope this helps, have fun tinkering!

Ok, I'll let others comment on the quality of your build list. However, after just going through my first build, I will give you a list of extra little things that you will probably need but haven't thought of yet because this is your first build. It's annoying to get all of your parts in just to realize that you're missing some battery connectors or you don't have a tiny hex screwdriver for some screws on your frame. You will probably need the following:

• Battery charger: you need a charger meant for LiPo batteries. A lot of people recommend the Turnigy Accucel-6 (it's what I've got). Note that this guy doesn't come with the AC adapter that plugs into your wall. Any simple 12V power supply will work. I use a 12V/1.5A adapter I found in a box that used to go to an old router, but you can power it with other things like a 12V lead acid battery or an old computer power supply.
  
• LiPo Charging Bag: I mean something like this. LiPos are known to ignite if over- or under-charged. I use one of these to charge and store my LiPos. I've heard of other people using things like old ammo boxes for storage. LiPos are fine when properly handled, but a simple LiPo bag could save your house if your charger malfunctions.
  
• Soldering iron: building a quad normally requires lots of soldering. You'll need one if you don't already have one. Most people recommend your soldering iron is at least 40W (the higher the wattage, the more heat it can produce). But I cheaped out with this 25W kit, and I haven't had any problems. If you don't get a kit, I would recommend getting some solder wick or a solder sucker so you can remove the solder if you mess up.
  
• Extra solder: it sucks to run out of solder in the middle of your build. You can pick up a couple of spools of 60/40 rosin core solder at RadioShack, and it will work just fine.
  
• Helping hands: this thing is great for holding things together while you try to solder them.
  
• Electronics screwdriver kit: you'll need a tiny screwdriver for screwing most things in your build. Not every screw is Phillips-head though, so get a kit that includes different sizes of hex and star bits too.
  
• Wire cutter/stripper: you will need this.
  
• Multimeter: you could get away without one of these, but they can give some peace of mind to know that you're not short-circuiting anything before you connect your battery and fry your flight controller.
  
• PDB: a power distribution board. This little thingy has solder pads all around it. The + pads are all connected together, and the – pads are all connected together. So you can wire your battery terminals to one + pad and one – pad, and all the other + pads will be 12V power and all the other – pads will be ground. These are useful for distributing 12V power to everything in your quad that needs it: each ESC, FPV camera, video Tx, voltage monitor on your FC, etc. The alternative to a PDB is a wiring harness, but I think those are kinda messy. That PDB link shows a 36mm PDB, the perfect size for the ZMR250 frame. (Side-note: the Crius FC you have in your list is 50mm x 50mm and is probably too big for the ZMR250 frame. I would recommend a 36mm FC like the Naze32).
  
• 18 gauge wire: it doesn't have to be 18 gauge, but that's a good medium size for most use cases on a quad. Use this for wiring a battery connector to your PDB among lots of other uses. Get both red and black.
  
• XT-60 connectors: these things. It's the same connector that is on the battery you listed. I would get a pack of both male and female connectors. You'll need one wired to your PDB to get power from your battery to your quad. I've also used these guys to power my FPV Rx and monitor with a separate battery.
  
• 3.5mm bullet connectors: these things can be soldered on to connect your motor leads to your ESCs. Some people prefer to solder their motors directly to their ESCs, but I like the bullet connector option in case you need to swap out a defective motor.
  
• Servo cables: depending on which FC and Rx you get, they may or may not come with servo cables. It might be a good idea to have 10 or so of these laying around. These things are used to connect your Rx to your flight controller, among other things.
  
• 5V buzzer: you might want a little 5V piezo buzzer connected to your FC to notify you of low battery voltage or to turn on with a switch on your Tx if you can't find your quad in high grass or something.
  
• Micro USB cable: a lot of flight controllers (like the Naze32 or the Crius) use a micro USB cable to connect to your computer for configuration. However, you are almost guaranteed that they won't come with one. You might already have one from an old cell phone charger, or you can pick one up at any electronics store. Notice that this is a micro USB and not a mini USB. Make sure you get the correct one, since a mini USB won't fit in the receptacle.
  
• Zip ties: get lots of them. Tie down your ESCs to the arms of your frame... tuck away wires so they don't get chopped up by your props... these things are used everywhere. I prefer black so they blend in with your black frame.
  
• Velcro: get some longs strips of adhesive-backed velcro. It's great for securing things to your quad that you take off often like your battery or your Mobius camera.
  
• Velcro battery strap: get some of these things for even more secure attachments of batteries and things.
  
• Heat shrink: used for insulating soldered connections. Get lots of this in a few different sizes.
  
• M3 sized screws, nuts, and standoffs: something like this is useful for securing your PDB and FC to your frame. I would get a nylon set, since nylon screws are a lot lighter than metal screws. Most of the holes on the ZMR250 frame are size M3, except for the motor holes. Those are M2, so you might want to get some M2 screws also just in case.
  
• Lanyard for your Tx: so you can hang your remote around your neck and pick up the pieces of your crashed quad with two hands.
  
• Eye protection: do yourself a favor and get some safety goggles to protect your eyes from dangerous things like hot solder and spinning blades of death.
  
  That's about all I can think of right now.

I have been using a Milwaukee 0490-22 for a few years and it is great for computers and printers, but it looks kind of pricy right now on Amazon. If you can find one for around $125, that would be a good deal. It has a battery life indicator on the screwdriver and an excellent charger. The battery has a twist lock, which is better than the plastic clips that require finger strength to squeeze and tend to break off. When working on laptops, you have to be careful when tightening screws because it can pop the thread nuts out, even with the torque limiter on 1. A 2.8V would be better for laptops.

It looks like there is a new design with similar features, the 2101-22.

As for getting to screws in tight places, I use a set of 6 inch bits that can reach through cables and around hardware. I magnetized the bits with a magnetizer so I can pick up and hold screws with them.

Good choice on the hand saw.

If you feel so inclined, you can make your own wooden Jorgensen hand screw clamps from scratch, e.g. http://www.amazon.com/Jorgensen-J-08-8-Inch-Screw-Clamp/dp/B00C1YXDTI/ref=pd_bxgy_hi_text_y. I have several that I made by sandwiching maple and walnut. They're very nice and have been real workhorses. Not cheap, though.

$77 is too much for a simple combination square IMHO, even if it is Starret.

Good choice on the sharpening stone & honing guide.

As requested, here's the composition of the rack:

• NavePoint 12U Network Rack
  
• TP-Link TL-SG1024: 24 port rackmount switch
  
• TP-Link TL-SG1016PE: 16 port rackmount power over ethernet switch (needed for the Wi-Fi access points)
  
• TP-Link TL-R600VPN: Rackmount router w/ dual-WAN and VPN
  
• Rackmount Power w/ surge protection
  
• Rack shelf: Used to hold modem and NAS
  
• Patch Panel: 24-port Cat6 patch panel (wires go in the pack via punchdown connection, and you run patch cables to the switches)
  
• 12" Patch cables: For connecting between the patch panel, swicthes, other on-rack devices
  
• Synology 416play NAS: Movies, music, pictures, etc. 32 TB in all.
  
  Elsewhere in the house/other useful parts:
  
  
• Keystone Cat6 jacks: one per bedroom, 4 in my home office, 4 in the media room (not built yet), 3 in the family room
  
• 1-, 2-, 3-, and 4-hole keystone wall plates: Buy the number of holes you want and just pop in the keystone jacks
  
• Blank keystone inserts: For when you have too many holes in the keystone plates
  
• Ubiquiti AC Pro x 3: Wi-Fi access points, roughly center of the house on each floor (basement, first, second)
  
• Punchdown tool: For doing the punchdown connections on the patch panel and on each of the keystone Cat6 plugs in each room
  
• Extra rack screws and washers
  
• J-Hook: There are two hooks on each wall, holding service loops for the Cat6 and Coax, respectively.
  
  Useful things I learned:
  
  
• I was originally going to run the wires myself, but never could find the time. Also Cat6 is expensive when not purchased in wholesale quantities (< 10,000 ft). So we hired a local electrician to run the actual wires. It took two of them about 1.5 days to run everything. This was well worth the money, since the project would have taken many months to do in the evenings/on weekends with a toddler running around.
  
• I did all the wall terminations. Since they were punchdowns, it was easy and took one evening after work. The electricians would have charged me another half-day of labor.
  
• I did all the network rack work. This also took one evening after work.
  
• Do NOT buy electrical/networking equipment from a big box hardware store. Always go to a specialized retailer, like an electrician supply store. Their prices will be 1/20th that of the big box store, you won't have to have anything shipped, and their employees actually know what they are talking about. So if you're looking for something that you don't know the name of, you can usually describe it.
  
• Newer construction may have fire breaks/blocks/stops which prevent fire and gases from traveling up the inside of the walls. This makes fire move more slowly and give you more time to evacuate. However, it also means you might need to drill holes/patch walls in order to run wires vertically.
  
• Put in a service loop. If you ever need to re-terminate for any reason (like replacing a patch panel), it will give you extra cable to work with. Do the same thing inside your walls behind the wall plates, since you might have to do the same thing there as well.
  
• Buy networking gear that is rated for the same speed (i.e., gigabit). Your network will only be as fast as the slowest part of it.
  
• Watch out for network loops. This is really easy to do and will cause your router to crash or perform suboptimally. I spent >2 hours debugging on of these as a result of connecting my router to itself by way of both switches.

I highly recommend getting a set of nylon nuts, bolts and standoffs. Great for quick crash repair and variable spacing of plates. They can be used as sacrificial parts so you don't break your arms or frame in hard crashes.

Also, extra servo connection wires, miscellaneous battery plugs & adapters, extra wire, hand tools for working with M2 & M3 hardware.

When you do get FPV going, right angle rp-sma connectors and stubby cloverleaf antennas for the video transmitter.

Just a few of the things I found useful.

I just want to sit at home and get what I want. It took awhile to find this trick but search on Amazon for "assorted". Pick the assortment size you want. There are also packets of the same size. The only problem is the Amazon search sucks, so the part description needs to be read very carefully. I only get those on Prime because of free shipping and usually getting good quality.

Machine screw assortment

Another assortment

Thank you! I knew there were kits out there like that, I just wasn't using the correct search terms I guess lol.

Found this, seems it should cover most things, until I run into something designed for m5 screws, but I'll cross that bridge when I get there lol

Repost, imgur ate the first image album.

The last 7 photos are from the first VR Crash Cart I built to help illustrate some of the assembly steps involved.

I wish I still had one. I swear those were just screws with rubber grommets on them.

I would bet money that something like these would work (they work great in Fractal Design cases too)


Edit: of course they aren't prime anymore. Anyway, what you really want are some antivibration grommets and regular old hd drive screws (thumb or not)

> So I should be able to pick some of those up at Lowes or Home depot?

Maybe.

You'll probably have better luck at a proper hardware store where they sell them individually. Especially for metric screws.

Option C is Amazon. Just buy a box and never worry again: https://www.amazon.com/VIGRUE-300Pcs-Assortment-Internal-Stainless/dp/B07M7CLTLT/ref=mp_s_a_1_1_sspa?keywords=set%2Bscrew%2Bassortment%2Bkit&qid=1568084041&s=gateway&sprefix=set%2Bscrew&sr=8-1-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUE1TTFKNE9RQjE0T1UmZW5jcnlwdGVkSWQ9QTAyMzY1NzcyRElXQkRGNDZOWUxGJmVuY3J5cHRlZEFkSWQ9QTA2NTc1NTcyWUFYREtHM0JFTjYwJndpZGdldE5hbWU9c3BfcGhvbmVfc2VhcmNoX2F0ZiZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU&th=1

Its just a 4-40 size screw, 7/8 inch long or less. I ordered an assortment from Amazon that has different lengths and, best of all, are hex-headed to make it easier to turn in the bridge. No more stripping the phillips heads.

https://www.amazon.com/gp/aw/d/B01BWN116K/ref=mp_s_a_1_4?ie=UTF8&qid=1519421551&sr=8-4&pi=AC_SX236_SY340_FMwebp_QL65&keywords=4-40+screw+assortment

Youtube is an incredible resource. Buy from Screwfix not B&Q, and don't forget about Amazon Prime for awkward stuff.

Don't go nuts and buy a 1500 piece tool box, instead get a small set of good quality tools, and buy as you go.

• A good drill (I love my Erbauer, however this is a bit cheaper)
  
  
• A set of bits and screwdriver heads
  
  
• A set of Rawlplugs and screws
  
  Congratulations, you can now put up shelves, hang mirrors, screw and unscrew anything, drill holes, put up curtains, blinds... etc etc etc
  
  Knowing how to bleed radiators is useful, as is replacing bathroom sealant. One thing that threw me was a 'Low Pressure Alarm' on my boiler. There's a little tap underneath that tops up the pressure by letting more water into the system.
  
  In general: Keep an eye on things and do preventative maintenance to fix things before it breaks or gets worse. Fixing a loose radiator in your own time at your own pace is much better than fixing it in a panic when it's finally fallen off the wall.
  

Pretty much all rack mount stuff. The box itself I made. You can get the AV Keystone jacks and 48 port plate at Monoprice. The rails, screws, additional plates and rack mounted power supplies from Amazon.

I had a pile of the keystone jacks from a previous purchase a couple years ago so I did not have to get a whole lot of them. The toslink keystone jack has a issue of popping out which is solved using a zip tie to hold it in.

Congrats on the new build!

You can buy the m.2 screw kit off Amazon https://www.amazon.com/ZRM-Motherboard-Mounting-Accessories-Screwdriver/dp/B07BVRGVWY/ref=asc_df_B07BVRGVWY/
my guess is they'd be even cheaper off eBay you don't mind having them shipped from China and waiting a couple of weeks to get it.

If that one doesn't need extra hardware, that's cool. Makes things easier.

The one I use does need some metric hardware for the threads. The nice thing is the threads are quite fine, so you make small adjustments in height.

I didn't feel like running to the hardware store sporadically to buy individual metric hardware for designs I found online and was printing. So I bought this $21 socket head cap screws assortment set from Amazon, with M2, M3, and M4 in different lengths:

https://www.amazon.com/gp/product/B07H4MG7TC/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1

I could buy a bunch of hardware as-needed for $21, but this gives me a lot of the common sizes that people seem to use in their designs.

Good point on the bearings! Didn't think of that. I'm actually eyeballing this guy for screws and whatnot:
https://www.amazon.com/Performance-Tool-W5226-1200pc-Assortment/dp/B000N35MMA/ref=pd_sim_60_2?_encoding=UTF8&psc=1&refRID=R8F1DNXT3TW51XTWFGZ5

I'd really just like to one and done instead of getting a little kit, only to find out I've got to run out to Home Depot to grab a fistful of some oddball size.

Dude I am so sorry. I thought I was still logged in, but I wasn't so I never saw the response. My bad.

I put 2 below to give you some options. Depending on the amount you need 1 is just like 4 and other is a larger set. I use these on my NAS with all of those HDDs as well as versions of the case fans. I also got 2 drive bays that slide in my case so the HDDs are not bolted directly to the case. Helps a ton.

slap some of these on it and anchor it like that, 2-3 along the top and 1-2 in the middle so do it i think

Not local, but amazon has a good selection

https://www.amazon.com/Nylon-Plastic-Machine-Assortment-160pcs/dp/B073F6Q66G

Those are nice.

These are my favorite.

I'd be surprised if they weren't in the box. There should be a riser and a screw.

ZRM&E 2 Sets M.2 SSD Screw Kit for M.2 Drives General M.2 Support Motherboard Mounting Accessories Screw + Hex Standoff Spacer+ Screwdriver https://www.amazon.com/dp/B07BVRGVWY/ref=cm_sw_r_cp_apa_i_wCMiDbVR46AC2

No specific one other than that they're plenty strong enough, and the main reason I recommended them is you shouldn't have to worry about size as the kit will have 100+ screws in various sizes IE:

https://www.amazon.com/Plastic-Metric-Machine-Assortment-M3X5mm/dp/B072K7WVPR

Edit: Just checked the metal sets, no difference in price, so it doesn't really matter unless you'd prefer plastic for any reason(Color,Conductivity, maybe damage to components if you wrenched on a metal one)

Also yeah 20mm is probably way too long but the set that goes up to it should work fine.

Those are brass M2 Female-Female spacers, I got them off of amazon.

I bought...

Been treating me pretty well. The case they came in is terrible but I’m in the process of designing and printing a new case 😃
