Simple case for arduino mega based occultation timer with Adafruit GPS shield.

What to print:
1x Top
1x Bottom
2x Side
4x Standoff

The sides slot into the top and bottom plates with a small amount of interference to keep them from rattling. The bottom plate should accept m2.3 screws for mounting the arduino. The standoffs should work with M3 or #4-40 screws threaded straight into them.
