Description

This mount is useful for hanging your PC under your height adjustable desk to keep cable lengths constant. WARNING: It lacks lateral stabilization, so it can swing a bit and will break if you want to break it. 

A worst case estimation of the tensile strength yielded 70kg for each of the 4 mounting segments.

Bill of materials

The required number of printed parts is also given in the STL filenames.

• 2x Top brackets left
• 2x Top brackets right
• 4x Bottom brackets
• 20x Clips

Besides the printed parts. You'll need:

• 3x 1m long wall rail for shelves (see picture)
• 12x 3.5mmx20mm wood screws with tapered head

Construction

• Cut 2 rails in half to have 4 symmetrical 0.5m long rails
• Cut the remaining rail to obtain 2x 22.5cm rails
• Assemble the 2 U-shaped swings by using the clips which slide over the brackets to secure the connection (see pictures)
• Screw the swing under your desk while keeping the rails parallel

Filament type and print settings

• I suggest using  PETG because it is quite strong but more importantly flexible. Do not use PLA because of creep and because it is brittle.
• Use 4 or better 5 perimeters, 4 or better 5 top and bottom layers and 40% infill.
• For print orientation see picture
• Supports are needed
