Creality Ender 3 Spool Holder

thingiverse

I found original Ender 3 spool holder just to short and to thin for most of my filament spools. All filaments I use have 50mm diameter hole and width of a bit more than 100mm. So those spools run with more friction and are worse secured as they do not lie flat on the holder. So I designed simple replacement which works for me much better than original arm. You mount it just to the metal part of the original holder and that's it. It is not geared holder but sliding one. But I found that bigger diameter of this holder works better and I am not sure that geared holder would be any better. I think that filament guide friction is much more important due to quick retraction movements. The spool friction doesn't count much when the filament is pushed to the extruder. And the design is extremely simple. I used only nut/screw customizer, the rest is all mine.
