Spool adapter for Ender 3 Pro (Read Description)

thingiverse

Tired of the old sad twitchy spool attachment system on Ender 3 Pro. Say no more. Here I bring you brand new attachment system for any spool with hole in the middle with diameter up to 8 cm. Takes about 5 hours to print with 15% gyroid infill and .24 layers when sliced by a Prusa slicer. I think you could get away with less infill and taller layers. Other supplies used: 4x bearings with 22 mm outside diameter and 8 mm inside diameter, 1x ~15 cm long threaded rod with 8 mm diameter, 2x 8 mm nut I suppose you could print all of above too, but I didn't feel like having the 8 mm plastic threaded rod break and the spool fall on the printing bed. Fit is quite tight on bearings so you might need a vice to press them in, otherwise I recommend enlarging a model in the slicer to 100.5% in X-Y direction You are a smart person so I trust you with the assembly ;)
