Spool holder for Prusa i3 - Bearing 608zz

thingiverse

Hey everybody! Here comes my new design for a spool holder that replaces the standard one on my Bq Prusa i3 Hephestos. I created it to address the issue of friction preventing the spool from rolling smoothly, so I used ball bearings 608zz type to ensure perfect spool rotation. This design should be compatible with most 1kg PLA spools, and I've already tested it with both Bq and Acccreate ones. Be aware that this model may require a bit of sanding for a better fit. I'm currently working on an optimized version, but I hope you'll still like it and feel free to share your pictures! Have a great day, fellow makers! Edit: I added a locking system to prevent the supporting branches from opening during printing, which will keep the spool secure. P.S. If you enjoy this design, consider showing your appreciation with a small tip - it would really help me buy more PLA to test my designs!
