Wanted a higher density option for a wall plate in the back of my server rack, 
designed to go into a 150mmx150mm hole in the wall, 
designed for m3 hardware.

If you decide to print it with no AMS you will not see the numbers at all, they are only recessed into the model -0.01mm so the slicer ignores them unless painted.

Fits standard keystones, i used coupler style and haven't tried it with punch down style keystones.
