On a Prusa I3 Steel the filament roll is dragged over a metal strip, see 1st photo right bottom side, and that doesnot roll very well. I replaced it with a cylinder with 2 ball bearings.
The outer diameter of the cylinder is 42mm and this may be to much for some of your filament rolls. The FreeCad files are included and can be modified easily.
What you need is:
- a rod 8.0 mm diameter 17 cm long (axis), I used an 8x1 mm aluminium pipe which I already owned.
- 2 ball bearings 608ZZ (8.0 mm
