Universal Filament Spool Holder

thingiverse

This is a design based on Foreverwinters universal quick change filament spool holder: https://www.thingiverse.com/thing:1241566 A couple of modifications: 1) The bearing mounting locations have a rib in them to reduce overall surface area when you press fit the bearing in. Makes them easier to mount. 2) The cone is shorter and steeper which allows it to work with spools with an ID or 50 to 80 mm, instead of needing to print an additional "enlarger" 3) There are two bolt variants. I use the longer variant on the smaller ID spools and the shorter one on the larger ID spools. Reduces printing times if you don't need the extra length.
