Rigidbot frame mount for TheLoneNut's PiTFT enclosure

This is a mount to put your raspi+pitft on any horizontal ~20mm square tube bar. This works well for a Rigidbot that uses a square tube frame. I wanted to put my pi up in the corner so that the camera module would have a good vantage point.
For anyone that's curious, this is the software I'm using:
