Having found a monitor stand design that I liked, I wanted to make it more flexible, and so I added brackets for a second level.
My model uses a shelf I had lying around, which was 16mm thick and 170mm wide. I cut it into two pieces to make a keyboard fit under the lower level and have the top one fit my monitor.
You'll need two bottom brackets and two top brackets for the design to work. No additional hardware required. I printed mine in Polymaker PolyTerra matte PLA for its snow-white look. The brackets with their current dimensions can be printed on a Prusa Mini two at a time.
Parametric Fusion 360 and .step files are included, so you can easily customize the brackets to fit whatever shelf you have.
Feel free to ask me if you want a version with different dimensions, I can easily upload more .stl files.
Happy printing! :)
