Modified Prusa i3 MK2 Spoolholder with ball bearing

I modified the original spoolholder of the Prusa i3 MK2 and added ball bearings.
The ball bearings ensure that the spool unwinds more easily.
It also prevents the spool from wobbling while unwinding thanks to the two ball bearings on each spoolholder.

I also included a printable ball bearing (nothing special) in case you don't have one.
It should do the job :)

You need to print the following parts:
1x Spoolholder_right
1x Spoolholder_left
4x Axis
4x Ball_Bearing (optional)
