Printing instructions

mount.step also referred to as a “plug”

This piece is carrying the whole weight off the monitor. I suggest you use the most structurally sound material on hand. I have used Prusament PC Blend.

  • Nozzle 0.4mm
  • Layer 0.15mm
  • Perimeters 15
  • Infill 100%
  • Supports: YES
Spacer 6mm

This piece is used to move the VESA mounting plate away from the monitor and create space for the nuts and bolts binding the VESA mounting plate with the plug.

There are no special requirements for this part, except for the height of the spacer to be around 6mm to prevent damage to the monitor. Print from non-flexible material.

 

Assembly instructions

3/ Place VESA mounting plate over the mounting spots

4/ Secure the VESA mounting plate to the monitor

Use nuts and washers according to the table above. The assembly should look like this:
