ReFiller - Filler-compatible, self-centering filament roller

After a new spool of filament vibrated its way off of the Filler on top of my printer twice in one morning, I decided to fix the problem.

This thing has two parts:

Spindle

The spindle is has high edges to keep spools from jumping off and a wasp-waist to keep spools centered. It only works with the new guide.

New Guide

The guide is a drop-in replacement for Filler guides. If you are already using Filler, you can print the guide first and swap it out. You can keep using your existing spindle with the new guide until the new spindle finishes printing.

I have also designed a horizontal 4040 extrusion mounting arm to use ReFiller on the Ender 3.

20%-25% is a good range for infill density. I recommend at least three walls/perimeters.

*3/11/2021 Thanks to dphagan's suggestion, I've uploaded a spindle body/plug combo that uses a hex-shaped plug. The plug comes in two tolerances, a rather tight 0.1mm and a more typical 0.2mm. Printing both will save some time and one of the two ought to fit. Let me know if anyone needs a even tighter tolerance. *6/25/222 Removed the old spindle body and plug, as it was causing confusion.
