Electron Prusa i3 Spool Mounts

pinshape

Summary This design has been modified for use on the Electron Prusa i3 clone with an acrylic frame. The top slot is designed to accommodate standard threaded rod, which should hold the acrylic in place when removing or replacing spools. If necessary, a small M3 screw can be drilled through to secure it tightly. The washers fit snugly onto the threaded rod, and using several nuts will keep them stable, providing a controlled rolling filament stand.
