Wall Mounted Spool Holder with bearings

A wall mounted spool holder that uses the 608 bearings and the 8*120mm aluminum tubing from the Prusa MMU spool trays. NOTE: I've included links to examples of these below in case you don't have these parts from the Prusa trays.

I came up with this Wall Mount for Prusa Multiple Materials 2S Filament Buffer solution because I couldn't fit five Prusa Trays on my desk behind the printer.

I needed pegs for the wall mount solution and wasn't happy with solid pegs so I figured out how to incorporate an axle from the trays into a wall mounted peg. It works great!

In response to a couple of comments I revisited this effort and created a customization macro for FreeCAD. I decided to update this posting to offer a variety of pegs I created to demonstrate how to use that macro.

• Single mount hole:

  • 'I' design elegant but tricky to mount
    

    • 'L' design is easy to mount

• Two mount holes:

  • 'Slim' design, minimal side tabs.
    

    • 'Sturdy' design, extended height side tabs.
      

• 'V4', the first design with very wide tabs because it was made to replace solid pegs that were already mounted.

• The design is minimalist so it prints much quicker than most wall mounted pegs.
• I made it possible to change the location of the bearings so one design covers all of my filament spools, even the ones too small for the Prusa trays.

You will need the following parts (or their equivalent) from the Prusa Filament Trays.

• 10x 608 Bearings
• 5x 8*120mm Aluminum Tubes

Here are some links as examples.
