Ender 3 Spool Holder With Integrated Bearings
Description
Has held 1kg spools well. Will accept spools with greater than 36mm hole diameter and up to 100mm wide. Everything prints without supports, but my advise is to use a brim when printing the shaft to keep it stable. Uses standard 6mm airsoft pellets as ball bearings. Print outer bearing x2 and assemble as shown in the photos.
