Filament Sample Pack Spool

Being new to 3D printing, I was anxious to try all the different filaments available. So I signed up for MakerBox and ordered some sample packs from a couple of manufacturers. Of course, they arrived loose, with no spool.

I promptly downloaded and printed a spool from this wonderful platform only to find that the diameter of all the "sample pack" spools I found were too small for the natural curve of the loose filament, causing them to unravel and tangle during printing.

I designed this spool to be larger than the curve of a sample pack, included a filament lock and extra tie-off points around the brim.

I hope you find it useful!
