Easy Desk Monitor Riser - Parametric!

Adding a monitor riser to your desk frees up extra space and raises the monitors for improved comfort. But many full-width risers for multiple monitor setups are quite expensive, so here is a cheap and easy to assemble alternative.

You will need:

• A shelf - I used an Ikea Bergshult 120x20mm shelf for £13. Price depends on your dimensions. Any shelf or similar block of wood that you can attach screw fixings into will work fine!
• Screws - the file is dimensioned for 4.2mm diameter x 16 mm length screws. You can change the parameters to fit any screws you already have, see below
• <100g PLA or your favourite filament

Customise:

The model is mostly parametric and the Fusion 360 file is provided, so you can easily customise the legs to fit your setup. You can change the user parameters under Modify → Change Parameters in the Solid edit mode. The main user parameters you may want to change are:

• height - the desired distance between your desk worksurface and the underside of the riser
• diameter - the outside diameter of the main part of the leg
• screw_diam - the outside diameter of your screw threads
• screw_head_diameter - the outside diameter of the head of your screws
• num_screws - how many screws each leg will be attached with

The screw holes and counterbores have clearance tolerance included already, so you shouldn't need to add any tolerance to your screw measurements.

Printing:

• The legs can be printed without support when the flange is on the bed. I used PLA with 3 walls and 30% infill - these parts are in compression so this is probably overkill.
  • Make sure to align the Z seam so that it can be hidden on the back side of the riser once assembled
• The jig can be printed however you want!

Assembly:

• The included jig file can be optionally printed to allow pilot holes to be drilled if necessary
  • Change the user parameters jig_hole_diam for your bore size and jig_edge_offset to choose how far the outer edge of the leg flange will be from the sides of the shelf
• The provided STL files use a height of 75 mm
