Creality Ender 3 Pro spool holder (low friction)
thingiverse
Credit goes to the wonderful original design https://www.thingiverse.com/thing:235925 (parts 3-6, unchanged). I just added a locking nut and bolt barrel ( parts 1-2) to make it fit my Ender 3 Pro spool bracket (original part). The hole of part 2_spool_bolt_barrel.stl is a bit tight for 5/16 bolt but it will go through using a wrench. You could use 2-spool_bolt_barrel_8mm_hole.stl for easy installation. Spool with 1kg filament runs quietly and smoothly on this holder, extremely satisfying. Instructions: In addition to the printed parts you will need: 1x 5/16-in 18 x 5 in Full thread steel hex bolt (in US) 2x 5/16-in x 18 Steel Hex Nut (in US) 2x 608 bearing (print or buy) I've printed and tested the 608 bearings (resolution 0.2mm, infill 100%) https://www.thingiverse.com/thing:4628063 (part 7), which work very well for this purpose. Or you can get steel bearings from Amazon.
