Mockup Filament Spool Holder w/Bearings

thingiverse

This mock-up spool holder is based on the original Ender 3 Pro spool holder that comes with the machine. I didn't like the original's resistance but liked its screw nut design, so I incorporated two bearings into it along with an axle. The attached 3MF file for Ultimaker Cura 4.6.1 includes the spool with all my settings and a support blocker on one side to make removing the supports easier. These supports wrap all around the spool, making them tricky to pull off but worth the effort as they result in high-quality prints and cylinders printed vertically. When printing, be mindful of the axle's thickness; one end is slightly thicker than the other, so insert the thinner end first into the corresponding side. I've included a printable file with all the settings I used, allowing you to print it however you prefer.
