I created this model in response to the high prices of monitor risers. This DIY project is meant to be used with any wood plank of 18mm thickness. The... dimensions I used for mine where 800x300x18mm, I used self tapping screws DIN75040 3.5-16mm, for the foot I used 20mm diameter felt pads to avoid scratching surfaces. I suggest using petg for a stronger parts and Everything is meant to fit without applying any force.
