Magnetic ball bearing spool holder - PL Design

thingiverse

This is a special spool holder, specifically designed for enclosures. It features 2 ball bearings that allow the spool to spin smoothly and effortlessly, preventing feeder motor preheating and enabling precise extrusion. In the bottom of the frame, there are 3 holes for strong neodymium magnets. If you glue three magnets to your enclosure with a 3M tape, you can easily attach or remove the spool holder. It is especially useful when you have multiple printers. To attach it, you can also use M5 screws if you prefer not to use magnetic attachment. There's also a version without ball bearings for those who want their filament to be slightly less loose. Both versions are easy to print. If you'd like to print the ball-bearing version, print these files: A_B Frame.stl (Supports needed) A BEARING NEEDED Filament holder print 2x.stl (No need for supports, print 2x) A BEARING NEEDED bearing housing print 2x.stl (No need for supports, print 2x) If you'd like to print the version without bearings, print these files: A_B Frame.stl (Support needed) B NO bearing Filament holder assembled.stl (Supports and brim needed) OR (Depending on your printer) B NO bearing Filament holder print 2x.stl (No supports needed, print 2x) I hope you enjoy my design. If you like it, consider donating the price of a coffee - I drink the more affordable one. Thanks a lot.
