This is a variation on previous model Filament Quick Clamp: https://www.printables.com/model/506814-filament-quick-clamp
- A rubber band powered filament clamp-on to prevent the spool from unraveling

This new model is different in the following ways:
- Wider expansion range: 49 to 74 mm (one size fits more spools)
- Not print-in-place to allow for tighter tolerances.
- Held together using 3D-printed screw threads.
- Rubber bands loop around the ends for friction to prevent clamp slipping out.
- Clip with fully straight path, no bending or kinks on the filament.
Assembly
Two rubber bands of around 5 cm are needed. A packet of mixed size rubber bands usually has some of this size.
Step 1) Get all the parts:

Step 2) Screw in the filament clip and loop the rubber bands as in this picture:

Step 3) Insert the shaft into the case and secure by screwing in the nut:
