Roller Bearing Spool Holder for Replicator 2

This is an improved Replicator 2 spool holder. The improvements include:

1) Turns very easily. the stiffness of the filiment even unwinds the spool a little.

2) No pinching to get the spool on and off, a slight tilt keeps the spool on.

3) Spool aimed slightly towards the filiment tube for better unwinding

4) Spool doesn't rub on machine, no matter if the large or small hole are outward.
