Disclaimer: I am still working on this and will update the files as I see fit. I am working on updating this post with the most recent iterations of the pulley system. I will add the most recent iterations soon when I finish testing them. I have modified the belt so it is now smaller and more durable when printed from TPU. It is a tight fit but it runs well and it should not strip. I recommend printing spare pinions because the teeth do wear away after heavy use. Print extra belts too. They eventually give way. This started out as having issues with my gears stripping or the pinion would fall off of the motor shaft. I have decided to move from gears to a pulley type system. Items included are the belt that should be printed from TPU and the Spur Pulley and Pinion Pulley both printable from PLA (Should probably be printed from ABS or PETG). These work better than the stock geared system (So far). They have held together and continued to work for ~1-2 weeks. The pinion is designed to fit a motor shaft with a diameter of 3mm and has a hole for a 3mm setscrew. Print with 4-5 top, bottom, and wall layers. Set infill to 100% for most solid part.
