Tripod Mount for 1.5

I made this for my Structured Light 3D scanning rig. I use David 3D scanning sofware. Use existing holes in print as a template to drill mounting holes in rail. The 5.1 mm holes are then tapped with a 1/4 - 20 thread. I recommend at least 3 perimeter shells to allow for the tap to thread. Open the holes in the rail to allow 1/4 20 through.
