Raspberry Pi Case

Just a variation of the thing with a few *ports covered* and different airflow. VESA 75mm holes. A hole for a camera lens, too. This is my first attempt at modeling for 3D printing. All comments and suggestions are welcome.

4x M2 x 4mm self-tapping to mount the optical sensor (untested)
4x M2.5 x 6mm self-tapping to mount the main PCB (untested)
4x M3 x 30mm + locknuts to close the case (tamper-resistant: Torx?)
