Case for Geekworm RPi camera clone

I use [Geekworm Camera with IR-Cut function](https://www.banggood.com/Geekworm-Camera-With-IR-CUT-Function-For-Raspberry-Pi-3B-2B-B-A-Zero-Available-At-Day-Or-Night-p-1102742.html) from Banggood. And it's in completely different form than RPi's original camera. So had to design own case for it.

You can put the cable through the slot on the top or on the back.

Didn't design the bed mount arm, because I use ball joint arm from [Thing:2756864](https://www.thingiverse.com/thing:2756864), that works amazingly well!
