Monitor Stacking Mount

This is a height adjustable mount I made to stack monitors on top of a Dell U3011. This adapter slips on the stand of the Dell U3011. On top I use a Dell 2412MB from which I used the Vesa mount plate to attach it to the stand. I also included a 100x100mm Vesa mount adapter for other monitors. I have this U3011 for a few years so the mount on newer Dell monitors has likely changed and would need a different bottom adapter to fit securely.
I printed this in Carbon fiber PETG.
