Filament Clip

After printing, we all have to store our filament correctly. One crucial step is to prevent it from unwinding from the spool. I accomplished this by threading the filament into the hole(s) at the edge of the spool, which also means losing 5 to 15 cm of filament each time I store it. However, I didn't like that and came up with a simple tool instead. The part with the hole fits over the end of the thread, while the other part can be clamped onto the next thread or winding. By moving the tool, everything tightens up perfectly. I'm fairly certain I'm not the first one to come up with this kind of solution, but I'm new to everything (Fusion 360, Slic3r, 3D printing, etc.). I like to practice and learn. As usual, I've included a factory file with settings for my Prusa MKS2 and rigid ink PLA filament. Update 2020/04/26: After receiving some complaints about the fit on different platforms, I've slightly enlarged the diameters.
