As seen in the GIF, the rotation works perfectly smooth without a bearing; for those of you who want to add a bearing, I uploaded an alternative print version for a 608ZZ bearing; note that I did not achieve a smoother motion with the bearing I used though. The inside of the device can store two replacement trigger needles in case it wears down, but this is simply a precaution. If you find any issues with my design, please send me a message and inform me! :) The assembly is pret
