About this 3D model

Raspberry Pi 2 case with ventilation and external enclosure screws. Having an issue finding small enough screws for the mounting holes in the Raspberry Pi 2, I have moved the screws outside the case body and will be fixing the RPi down with foam mounting tape (3M command strips.) Additionally the screws no longer go all the way through the case, they just thread into the bottom piece. I didn't want to counter sink the screws on the bottom or add rubber feet to avoid scratching stuff.
