Wall Mounted Spool Holder with bearings

thingiverse

A wall-mounted spool holder that utilizes the 608 bearings and 8*120mm aluminum tubing from the Prusa MMU spool trays is created. Links to examples of these components are provided below for reference. I came up with this solution because I couldn't fit five Prusa Trays on my desk behind the printer. I needed pegs for a wall mount solution, but solid pegs were not satisfactory, so I figured out how to incorporate an axle from the trays into a wall-mounted peg. It works great! In response to several comments, this effort was revisited and a customization macro for FreeCAD was created. A variety of peg designs were developed to demonstrate how to use that macro. - Single mount hole: - The 'I' design is elegant but tricky to mount.  - The 'L' design is easy to mount.  - Two mount holes: - The 'Slim' design has minimal side tabs.  - The 'Sturdy' design has extended height side tabs.  - The 'V4' design has very wide tabs, made to replace solid pegs that were already mounted.  The design is minimalist, making it print much quicker than most wall-mounted pegs. It is possible to change the location of the bearings, allowing one design to cover all filament spools, even those 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: [300mm 8mm Aluminum tubing](https://eugenetoyandhobby.com/shop/k-s-9810-heavy-wall-aluminum-tube-8mm-od-x-76mm-wall-1/?gclid=EAIaIQobChMI44zYo_yv4gIVuh-tBh33fgpZEAQYASABEgKvgPD_BwE) - x3 = Cut your own [608 Bearings](https://www.amazon.com/Groove-Bearing-Bearings-Skateboard-Printer/dp/B07FGVFN6F)
