Multi-Spool Filament Clip

prusaprinters

<p>After several months of tripping over spools scattered around the lab, I finally got them all mounted onto a single bar to simplify the swapping process, but I still had to fumble around with all the filament ends, which were each secured to their own spool when not in use. So instead, I came up with a simple solution that keeps all the ends tidy and in easy reach.</p><p>Holding the strands at the back of the frame keeps them from obstructing the active filament path, which feeds in front.</p><p>I printed mine in PLA with 2 perimeters at 0.3mm layer height, standing on end, with no supports, but added 3mm of brim to keep it secured to the bed.</p><p><i>Note 1: When securing a filament into the holder, the end needs to be clipped and tidy. Messy ends will not fit. But I view this as a feature rather than a bug, because tidy filament ends also cause fewer problems when loading.</i></p><p><i>Note 2: Tuning the lip that controls the snap fit is a bit tricky, given the wide variety of plastics that everyone is going to print it with. So rather than be the cause of a hundred useless prints going to landfill, I've leaned slightly toward too tight a fit rather than too lose, because too tight is easy to fix. Just file down the lip until it goes on.&nbsp;</i></p>
