A simple yet strong monitor stand compatible with IKEA BURHULT. This is an affordable and elegant solution when it comes to desk organization. Height of the stand is 90mm, with 75 mm space underneath it.

IKEA BURHULT is supposed to be 23 1/4x7 7/8 " (59x20 cm), but weirdly enough the one lying around in my apartment was 54.5x19.4 cm. The model included is made with the actual dimensions in mind, with a 0.5 mm offset all around. I've included a SolidWorks model with equations set for the width of the panel as "A". Change that if the model you have is not 20 cm wide.
0.5 mm clearence on all sides is a bit too much but can be compensated by adding a few rounds of scotch tape or paper cards cut along the length or both until you have a snug fit.
I used 20% infill and 2 wall count. I would recommend more infill but 20% is functional. I use it to hold a 32" monitor.
