Raspberry Pi camera case/enclosure (remeshed for low vertex count)

##File History
This is just a lower poly count version of VGer's awesome case (thing:92208). The bottom is a lower poly version of thing:158664, one of the former object's derivatives. I had trouble when I tried to print these parts - it even crashed repetier-host, a first for me!
##Decimation Process
I ran both parts Meshlab's quadratic edge collapse decimation filter (set to 50%) a few times, I was able to get it down significantly! The top part I got down to 556 vertices (from 37K), a
