I specifically made these according to the height of my desk and chair to fit perfectly for me, but they might work for you as well. Be sure to print with at least 4 vertical shells for stability. The arm is a single piece designed to fit a mk3 print-bed. I also used weldbond universal glue to add a layer between the desk mount and the desk before I screwed them in. They friction fit into some dovetails but have an alignment hole too if you want to put a pin in there.
*Invert the file “Combo” to print the Left side.
