i made this to hold the filament in place to keep from unraveling from the spool.

there are 2 ways to secure the filament:

1. is to push the filament into the top slot after tightening the clip to the spool.
2. place the filament into the lower slot as you tighten the clip to the spool. this will make sure it is securely tightened in place.

no supports.
