Loose Filament Spool Holder (for Filament Samples)

pinshape

I'm always buying up various types of filament samples, which often come without any spool to speak of. I've tried out a bunch of different spool holders, but what I really needed was something specific - and I wasn't entirely sure why that was the case. This is my first stab at it, so I may revise things later. Loose coils can be a real nuisance, either tangling up or simply being unusable due to their shape. Since my printers are set up in a certain way, they need to sit on a spool holder, which just adds to the problem. My design features tabs at the front that you can easily rotate to let loose filament coils slide right on - it's as simple as rotating the tabs towards the center, sliding the coil onto the three pegs, and then rotating the tabs back to their original position. The central spool is 55mm in size, while the outer pegs are designed for about a 140mm coil. This was specifically made to fit the Algix3D loose filament coils I already have on hand - if you need different dimensions, just let me know and I'll see what I can do. There are actually two versions of the main spool holder - I've only printed the one with the solid center spool, in an effort to save some filament. The other version has holes in it, but it should still work fine. You'll need to print out three tabs, which will simply press into the holes. It may take a bit of force to get them in there at first, but once they're inserted, they should rotate easily and stay put - you won't have to worry about them coming loose without some extra effort. There's also a v3 clip available that has a slightly larger tab for insertion. As far as print settings go, 50% infill worked just fine for me - but feel free to adjust it as needed to suit your own preferences.
