These are some additional parts I customized from from LeHof's design.
- made the arm flat on the bottom to avoid wasting time with supports - made a shorter version of the arm - made a slimmer version of the monitor mount - made a smaller, slimmer version of the monitor mount (as the original would not fit in my Dell monitors - made a 4 way point, as I needed to be able to interface 2 stands with two monitors
Print the monitor mounts at 100% infill. The arms could be printed at 50%, just be sure to add extra perimeters (I used 5)
Warning: I am not an engineer, so I take no responsibility if you break your monitors.
I also had to create a modified version of a Dell Monitor Stand adapter, found here: https://www.thingiverse.com/thing:4864597
Requires some M8 (8mm) bolts and nuts - can't remember the length, but 80mm should work.
