Spool Retention Clip

I was having a problem with my filament spools moving back and forward, thereby allowing the filament to get wrapped around the spool holder and sometimes causing a jam, and even breaking the filament.

I create this small clip to attach to the spool holder and clamp tight enough to allow a little movement of the spool, but not enough to case the previous problems.

The two pieces are held together with a couple of 5mm binding screws.

So far this design is working with 100% sucess.
