Most 3D printers come with a pretty basic filament holder — often little more than a bar to hang the spool on. [Ivan Miranda]’s 3D printers run bigger spools than most, though, so he had to craft an altogether more serious solution.
Unlike most of [Ivan]’s creations, the spool holder isn’t actually 3D printed. For this job, he turned to a laser cutter instead, cutting the parts out of 5 mm plywood. A handful of layers of wood bolt together to form the frame. The frame holds several bearings for the outer rims of the spool itself to ride on, allowing it to spin freely as the extruder tugs on the filament. Reducing the rolling resistance of the spool is key when working with such large, heavy spools, and reduces the chances of the filament not feeding properly.
It’s a tidy example of a tool built quickly and easily using a laser cutter. It pays to remember that while 3D printers are great, a laser cutter can often turn out parts in a short fraction of the time.
