Mini spool for 10m filament

I bought a set of 3d pen filament to have a supply of lots of different colors for small details like letters and logo's on multi color prints. These as well as a bunch of filament samples don't have a spool and get tangled easily.

To fix this, made these small spools to fit these 10m lengths of filament. To further avoid tangling and store them a bit neater I also made a custom filament clip that clicks on the side of the spools.

After printing, the two halves need to be glued together (I used CA glue). Hook the end trough the small hole in the hub and start winding. Winding the full 10m by hand takes less than 3 minutes. To place the clip I've found it the easiest to clip it on the filament first, then push it on the side of the spool.

UPDATE 6/9/24

Added an alternative version with holes to secure the end of the filament instead of the clip.
