grabcad
Filament spool holder made to fit above 30-bot top bar(of 30mm width), without the use of threaded rods. Also incorporates a filament guide to prevent unraveling of filament preventing mess and tangling. Spool holder is in 2 parts, so that bigger or smaller spools can be used just by adjusting position.
