Ender 3 Spool Spacer and Retainer

thingiverse

This is my take on a spool spacer, taking up the slack between common filament spools and the Ender 3 spool holder. I included all of the necessary SCAD files to modify this design, as spools often differ in inner diameter. The spacer embosses its outside diameter on the retaining hub. This is a description of the parts. 1. Spool spacer - takes slack from spool holder to spool hub, 2 needed 2. End Spacer - press fit to provide retention to the spool, choose this or the two below. 3. End Spacer V2 - threaded to provide retention of the spool, 1 needed plus 1 nut. 4. End Spacer Fixing Nut - retains End Spacer V2, 1 needed if choosing #3. To create the whole project, you need to print 2 spool spacers, and either #2 or #3 AND #4. The scad file is included, and is super customizable, with all needed parameters in the heading as variables. Also available on Github: (https://github.com/jdmm72/3D-Printing)
