ELP USB camera case

[This is a remix of https://www.thingiverse.com/thing:2751705]

I liked the original design, with the 1/4" attachment, but I had a few issues:

1. Why have the screw holes go through the front case?
2. The 2.5mm screws (and holes) means that the threaded PCB board of the camera also attaches to the screws. This makes it difficult to get a nice, clean closure.
3. The screws aren't indented, sticking out ugly in the back.
4. This thing gets hot, so I think it needs more heating holes.

So, I adjust all this in Fusion 360, and this the results. It attaches with M2 10mm screws, which will just screw in from the back into the front holes, and will lock tightly (the holes in the front part is slightly smaller, to get a good grip).

It should print without supports, although, unless your printer is awesome at bridging, you probably want supports for the 4 indented screw holes (for the screw heads). The bridging here is awkward to say the least, and likely will fail a little bit. The ventilation holes in the top and the side should print fine without the supports, any decent printer / slicer should bridge that without problem.
