Filament spool holder for 2020 extrusion with 3mm panel

Mount for a Ender-style spool holder with spacing for a 3mm panel on top of 2020 extrusions. This thing is based on Renaissance3DStudio's redo of the stock Ender spool holder mushed together with the bottom of the Voron 2.4 spool mount. I borrowed the "teeth" and screw hole locations from Voron, grafted them onto the spool holder, and added space for the 3mm plexi panels on the outside of the Voron. This should fit on anything with a 2020 extrusion and a 3mm panel on one side. Attaches with an M5 screw.
