Bearing spool holder with adjustable brake

Spool holder with adjustable brake (to avoid uncontrolled unroll) for 51mm spool.

For making it you will need also:
- two bearings 6905 (25x42x9mm),
- any compression spring with dimensions more/less similar to standard extruder spring, but with thinner wire, original is too hard. My spring has a wire 0,5mm , I found it somewhere in my workshop, between a lot of "things that can be useful"
- slice of felt (thickness 1-2mm), which has to be glued at the end of brake.
