Simple sample spool holder

This is a holder for a sample spool of filament. Customisable for the hub and spool diameter and the number of arms.

You will need to print one hub and three arms (or as many as you've customised), and screw them together with M3 bolts. I found the holes were the right size to hold the thread and didn't need a nut, but your results might vary.

Drill some 2mm holes in the arms to hold the filament ends.

Update: V2 has fixed a couple of dimension errors I was having, and I've put holes
