Ball Bearing Spool Holder Ender 3 S1 Ender 2 Pro SV01

Ball bearing filament spool holder for Ender 3 S1 and Ender 2 Pro. I assume this fits A LOT of creality printers but I only have these 2 to test it on.

One maker has confirmed it fits an SV01 Pro

This keeps the filament moving smoothly to help eliminate ringing and artifacts in your prints and also makes cardboard filament spools much easier to work with. I have noticed they develop flat spots in them and dont roll so smoothly. The ny-lock nuts allows you to tension how it rolls. Loosen the nylock on the end of the Spool Screw for easy rolling or tighten to keep the filament from rolling too much or rolling backwards.

If printing the Spool Screw and Spool Nut together change your “Support Overhang Angle” setting to 70 and make sure “Support Placement” is set to Touching Buildplate.  Otherwise you will have support material to clean out of your threads.  Print with 0.16 Layers and you shouldnt have any cleanup to do on the big threads. Print with threads pointing up.

Mount adapters are printed face down, 0.24 layer height is fine

3mf files included for both.
