Filament Roll small diameter

Because of the low rim next to the bearings, my spool kept running of the roll and got stuck between the roll and the bearing. This resulted in failed prints.

I used FreeCAD to sketch a roll with a smaller diameter, so the spool stops running of the roll. The part has been redesigned a couple of times, so it can be printed without supports. Make sure to use one of the roller inserts from the original part.
