Reddit mentions of NovaMaker 3D Print Removal Tool with Sturdy Wooden Handle，Tool Kit for 3D Printer Spatula Palette Knife Painting Enhanced Version Pack of 3

I'm really sorry you've lost your fingers. That's so horrible. I myself work in a shop using powertools on a daily basis so I know the risk and how easily it can happen, it's one of my greatest fears and I wouldn't wish it on anyone. I hope you're coping alright all things considered.

There are definitely resources out there for you and people who can help. Here is one, I know there are more out there. I think there's one in particular I couldn't find.

Here's a list of a bunch of .stl databases.

Here's another list.

There's probably some overlap in those but that should help. I googled 'list of 3d model repositories' to find those, you may find more with similar searches like '.stl databases'. Add 'medical' or 'prosthetic' in there too, combine them and you should find some helpful search results.

There are also places online you can pay people to print stuff for you. But honestly if you find a model that you think works for your hand situation, please pm me! I would love to print it for you and send it to you probono if you want something from asap until you can print your own (I imagine you probably will have alterations you'd like after the 1st attempt) after you've figured out your printer. I'd be happy to help you get started as well if you have any questions at all. I have gone through the initial learning curve myself for about 2 years now so I know what you're in for challenge-wise. Check out the r/3dprinting subreddit, there's a lot of helpful folks over there, there also might be a specific subreddit for your exact printer. Yep, just checked, I believe it's r/MPselectMiniOwners. I've also gotten lots of help from 3dprinting discord channels (namely '3dprinters') Discord is a chat server program incase you're unaware.

Tools and materials wise, you will need only a few basic hand tools and filament. PLA will probably do just fine for your situation (you can use more durable filament later, PLA is just the easiest to work with and best for prototypes. Hand tools that I use are a metal spatula like these, and a pair of snips like these. I also regularly use 99% (highest % is best) isopropyl alcohol to clean my printbed surface. Also get a nice gluestick to help print adhesion to the printbed surface if you run into adhesion issues. That's about it, I have other tools and stuff I use but those are my most frequently used. You might want to get a decent set of hex head wrenches these are the ones I use, they work a lot better than allen 'L' style hex wrenches for working on your machine. That's assuming your machine uses hex head nuts though.

Also, Fusion 360 is the program I'd recommend looking into if you're trying to do your own modelling. It's actually pretty easy to learn, I used a site called udemy.com which offers cheap lessons (~$10 a course sometimes cheaper) that are very helpful. Fusion 360 is free for hobbyists.

Seriously though, please don't hesitate to pm me, I'd love to help you out if you're interested in that. :)

If printing with bed heat, I typically let the plate cool down to the 20-30c range and then add some isopropyl alcohol around all of the edges of the print touching the build surface.

Let it sit for a minute or so and then use something without a sharp edge to work under the print and free it. Go slowly and keep whatever tool you're using parallel to the bed/print so that you don't gouge or tear the bed. Tools like this are what I use: https://www.amazon.com/dp/B0746JMH4J/ref=cm_sw_r_cp_apa_i_UQ6nDbDRRQDZB

If you're not using a heated bed, just skip the waiting for it to cool part. 😀
