I know it's cool to print your own, and these are a little smaller in diameter, but if you don't have M3 nuts readily available (and have Amazon Prime) and will have to buy nuts anyway, you may as well just get all-metal screws like this and be done with it. They work great on my MP-i3.

Amazon. Around $1 a piece. Make sure they are metal threaded not just plastic entirely.

They wont be the only thing holding down the panels , if even at all. They’ll be held at a determined height using ( https://www.amazon.com/dp/B07PLTQ5CN/ref=cm_sw_r_cp_api_i_MUF0DbWNHHDJ9 ) and L brackets but thanks for the concern!

I found this control knob on Amazon that works great.

That's almost certainly a custom machined piece. You can see in the breakout in the lower-left corner that it's 3 pieces: a pivot rod and two endcaps.

You might be able to use something like this along with a short piece of threaded rod: https://www.amazon.com/JW-Winco-Stainless-Threaded-Diameter/dp/B00A9N0DUU/ref=sr_1_6?s=industrial&ie=UTF8&qid=1483477353&sr=1-6

Mine are t-track bolts which I’ve put together backwards and locked with regular 5/16” nuts. A threaded insert is placed in the outer leg for the t-track bolt to thread into. Ideally you’d use something like this

Does this look like it might work?

It look like these or something similar: https://www.amazon.com/dp/B006M70BM2/

I have a Fastenal in McFadden-Dale here in town that has them but here's ones on Amazon

I've emailed my 3D printing friends to see if anyone will print a pair for me.

I've removed my Rift headphones and have the Knurled M3 nuts showing up Monday.

These match the ebay ones you shared

Search for "kme knob" on amazon.

That finds this for example:

Unfortunately they want $9 to ship it, so not super cost effective, but the description has the thread info you'd need to source it locally.

So I don't know whether these will work or not yet, but I ordered them and I am going to stop at Home Depot and get the rest of the parts when they come in and I will report back how I manage with these....

Yup, I actually bought an XT8 base off ebay and had to return it because it didn't fit the XT8i tube at all.

I did just purchase an XT8 Plus base off ebay and the XT8i tube fits almost perfectly but the threading on the tensioning knobs is different than the threading on the XT8i tube. The XT8i tube has 1/4-20 threading and the tensioning knobs that came with the base are something different and larger.

Also unfortunately, the side bearings on the telescope do not line up perfectly with the holes for the tensioning knob. I guess the XT8i tube sits a little higher than the XT8 Plus tube.

This weekend I will buy something like these that will actually fit into the side bearings of the tube. I will also need to drill holes in the side panels of the base about an inch higher then the ones there now so the tensioning knobs can reach the side bearings on the telescope - otherwise I think it will work!
