Prusa i3 MK3S Spool Holder Bearings

pinshape

I've designed two custom bearings that can be slid onto the stock i3 MK3S spool holder since this design isn't working effectively. The bearings are suitable for ColorFabb 750 gram spools and for the spools shipped by Prusa with their printers, which I believe are all 750 gram silver PLA spools. The tolerances on the bearings are pretty tight (±0.15mm), so ensure that your printer can print these accurately. I printed mine in Dutch Orange PLA from ColorFabb using the stock PLA/PHA profile in PrusaSlicer at a 0.2mm layer height, and I didn't encounter any issues. You likely need to "loosen" the rollers slightly after printing, which can be done by attempting to gently pry them apart. Once every roller is free, you should feel the bearing spinning smoothly. If you'd like to support me for the designs I publish at no cost, please consider using my AliExpress Affiliate Link when purchasing something from AliExpress. It won't cost you anything extra but will greatly benefit me.
