Prusa i3 Spool holder (yet anotherone)

Nice fitting to the prusa i3 6mm frame. There are these other parts you get off the shelf:

• 2x 608ZZ bearings (22x8x7),
• 150mm 8mm threaded rod
• 4 x M8 nuts
• 4 x M8 washers

Print 2 of each.

Side holders are nicely fitting to different sizes in spools inner radius.
The bearing fits snuggy, remove the support material. Use the washers to provide clearance for bearing.

Updates:
-support those spools with very small inner diameter (30mm).
-bracket now has a clip on leaving some space for nema on extruder when is on highest position.
