Optomechanical mount collection

Collection of optomechanical mounts.
- 1x5" board for mounting optomechanical components. All five holes are recessed to fit the screw head. The three in the middle is oriented one way, and the two on each end are oriented in the other way. I made it because I needed a 1x5 corner reflector to sit on a 3x3 motor controlled stage.
- 1x5" board with supports under the wings. Other than the wings, which will fit around a 3" wide moving stage to provide support, the characteristics are identical to the flat 1x5".
- 1x4" board with two holes to mount posts, spaced 2" apart, and 2 holes to mount the board to the optics table.
