Vesa mount for monitor arm

Computer monitor vesa mount for common monitor arm desk mount. Has holes for 75mm x 75mm and 100mm x 100mm mounting styles and includes a generic spacer. The space can be scaled for different thicknesses, depending on available mounting hardware.

I added some loops which can be used for cable management, big enough for zipties or hook and loop cable management wire ties. 

Print with monitor side face down and supports touching the build plate. 3 walls and any infill percent should be good enough.
