i swear i made sure these btus are the exact same size as the ones this shell is made for, but the holes in the print are too small to press them in, 0.7mm is way too much difference

@snacks as in ball transfer units? i went with the expensive bosch-rexroth ones for my trackball… surprised i even found a place that would sell those in quantities smaller than 10000 units

@mia i searched for ages and could only find them in stores overseas. Obv i found a place that sells rexroth ones after putting in my 30 euro order at fucking kugelrollen-shop.de. One of them doesn't spin as freely as the other 2 so i might still try ordering the proper ones.
But for now i'll try modifying the stl to make this stuff fit

@snacks they are not properly lubricated from the factory. you need to clean and add proper lubricant

@mia if anything lubing it through the hole at the back seems to have made it worse
somehow

@snacks did you clean it with a good solvent that gives you 10 types of cancer upon eye contact?

@snacks took a very thorough cleaning and a lot of spinning (under a bit of load) to get mine running smoothly
