Material Sample Spool

I ordered a couple of ColorFab sample kits and had to come up with something that would hold the material for printing. This is a simple design that is easy to print. This part is designed as a push fit but I used super glue to secure the arms into the hub.

As this spool has very little weight there is a chance that the filament will cause the spool to spin and unwind. I prevent this by pushing some kitchen paper inside the hub. This increases the friction between the hub and what ever it
