Multi-spool holder for Wall Control Peg board and Prusa MMU2s

Multi Spool holder for use with Wall control pegboard.
This is an updated version of my previous spool holder (https://www.thingiverse.com/thing:3329292). Changes include:

Complete redesign from scratch.
Stronger build
Removed the brake that is no longer required for MMU2s
Assembly and disassembly are much easier, and no longer result in broken spool arms or spool wheel pins.
The new design still uses the 608RS bearings, but in addition now also uses the metal rods that come with the Prusa MMU2 / MMU2s spool holders.

Print:
Arms = Number of spools +1
Spool Wheel = Number of spools x2
Spacers = Number of spools x4
(optional) Bearing caps = Number of Arms

Ie: if you want 5 spool holders to use with Prusa MMU2s, then you would need:

6x Arms
10x Spool Wheel
20x Spacers
6x Bearing Caps (Optional)

Assembly:

Mount the arms on the wall control pegboard at the appropriate distance - 4 slots between arms (total width of six slots)
Insert spacers into both ends of each spool wheel.
Insert metal rods through spacers and spool wheels.
Place a bearing on each end of the spool wheels on steel rods.
Place assembly on arms
Put the bearing caps on top of bearing/arm assembly (optional)

Print instructions

The arms need to be printed with supports for the wall control hook, as well as the cavities where the bearings are inserted. The bearing caps also require supports for the cavities where the bearings fit.

The spool wheel can be printed with no support. The end with the groove for the spool to ride in should be placed on the bed.
