The other two eSun Repwinder spacers I found on Printables did not fit my eSun Masterspool, so I created my own. The eSun Masterspool requires a 6mm spacer, while normal eSun spools require a 16mm spacer.
This model is parametric, so it can be customized for any spool you have. It features notches/tabs to lock into the Prusament spool ring and base cap. It is recommended to print with 0.2mm layer height to retain the resolution needed for the spacer notches.
The author marked this model as their own original creation.
