Filament Spool Holder w/Brgs (Ender 3 S1 Pro)

thingiverse

This is a Filament Spool Bracket with Bearings for the Ender 3 S1 Pro. I used skateboard bearings that I had on hand. Special attention must be made when slicing the shaft (Cura) because Support must be Blocked for all except the top end of the shaft. For the bearing-shaft cavities, I used Bridging instead of Support. Here is a video that describes using bridging to prevent support. https://www.youtube.com/watch?v=IVtqAn4oDDE&ab_channel=Vector3D The blue surfaces in the images are Bridges. I used rafts for all the parts. The Cap is printed with the open end up so no support is used. I used the mounting detail from this part https://www.thingiverse.com/thing:5391131.
