This piece adapts a standard VESA mount to the 85mm M3 holes on the bottom of an Intel NUC computer.
I printed with 0.4 nozzle at 0.8 extrusion width and 0.25 layer height. I chose to disable the top and bottom solid layers to let that sweet hexagonal infill show through, but it would probably be stronger the normal way.
It was a little wiggly, so I ended up adding some double-sided foam tape between the monitor and adapter, but I wouldn't want to trust everything to just tape.
