another printable spool - 2 sizes
thingiverse
two sizes of filament holder spools, 170mm and 120mm. the halves snap together with a tooth in one spot to prevent the outer wheel from spinning. i made the design to be sturdy while using the least amount of material possible. i started the print and walked away without watching it and came back to horrible overextrusion (see large spool in picture) and it still worked fine so the design held up pretty well.
