Yet Another Universal Spool Holder - Ultra Complex Edition
Description
I designed this spool holder for fun with the following constraints: 1. Fits widest possible range of spools - Spool bore diameter from 31 to 60 mm, thickness up to 100 mm, flange diameter up to 300 mm 1. As low friction as possible, spools must fit exactly and not dangle 1. Spools must be locked into place with no chance of being knocked over 1. Must be compact and take no more space than what is available on my printer's frame (Prusa i3) 1. Minimum number of non-printed parts - Only 2 off-the-shelf bearings (I used these: https://www.conrad.ch/fr/roulement-a-billes-radial-ubc-bearing-626-2z-198844.html, but any other bearing should be very easy to adapt), fastening is done via plastic fits with no extra fasteners Print and use if you dare the complexity! Check out the original design: https://cad.onshape.com/documents/846d2fdabb725c87aadb4a67/w/edc1572a60faf9a7fdcf4df9/e/a1a614158931a51df0a22a16 In all seriousness, you should probably use a dual cone holder instead of this, such as: https://www.thingiverse.com/thing:2070272. It is a better design overall.
