Yet Another Universal Spool Holder - Ultra Complex Edition

thingiverse

I designed this spool holder for fun with the following specifications: 1. Fits the widest possible range of spools - Spool bore diameter from 31 to 60 mm, thickness up to 100 mm, flange diameter up to 300 mm 2. Minimizes friction as much as possible, ensuring that spools fit exactly and do not hang loose 3. Locks spools securely into place with no risk of being knocked over 4. Maintains a compact design, taking up no more space than what is available on my printer's frame (Prusa i3) 5. Uses the minimum number of non-printed parts - Only 2 off-the-shelf bearings are required (I used these: https://www.conrad.ch/fr/roulement-a-billes-radial-ubc-bearing-626-2z-198844.html, but any other bearing should be easily adaptable), fastening is done via plastic fits with no extra fasteners Print and use at your own risk due to the complexity!

It is a better design overall.
