Electron Prusa i3 Spool Mounts

Remixed and adjusted for use on the Electron Prusa i3 clone that has a acrylic frame. The top slot is made for standard threaded rod.

It should grab the acrylic just enough to keep it in place as you remove/replace spools. If it moves too much you can drill through and add a M3 screw to secure it in place.

The washers will fit nicely on threaded rod and if you use a few nuts to keep them in place it will give you a nice and somewhat controllable rolling filament stand.
