Thingiverse
I wanted to integrate a Raspberry PI case from a kit into a VESA (75mm) mount! Print off two copies of this STL and use some M4 screws to screw it together! I've only tried this with small displays (7"), I don't think this will work with a full size TV, but this should work with many other lighter VESA accessories.
