PiKVM Case for Pi 2 W w/Vents

This remix improves on the original Raspberry Pi 2 W case (linked below) by addressing heat buildup during normal operation. In the stock design, my Pi 2 W stabilized at around 52°C. I added a series of triangular ventilation openings to promote airflow through the enclosure, which reduced temperatures to roughly 42°C. The triangular pattern was chosen so the vents print cleanly without requiring supports.
