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 ;)
