Raspberry Pi HQ Security Camera Mk1

This is a case for a security camera design based on a Raspberry Pi and an HQ camera module. See the GitHub repository for the project for additional details and software to stream video with.

I printed this in white Buddy3D PLA, which seemed to work pretty well. I don't recommend this design for outdoor use regardless of filament type since the side ports on the Pi face upward, so it will not be weather-resistant no matter what. I plan to address that flaw in a future iteration.

Layer height should be 0.2mm at least for the internal frame piece. That will make sure the downward-facing nut recesses print cleaner. You will also need the following fasteners to assemble the case:

• M2.5 hex nut x10
• M2.5 screws, 10mm long, x8 for attaching the Pi and camera to the frame.
• M2.5 screws, CSK, x2 for keeping the case shell closed (I used 10mm screws here too because that's what I had handy, but shorter ones would be better).

You will of course also need an HQ camera module, a cable for it, and a Raspberry Pi with storage and power. I used a 3B+ and designed everything around that, but it should be straightforward to create I/O shields for different models (or if you don't mind bigger holes in the case, just leave those out and it should be compatible with any Pi).

Assembly instructions:

1. Print all parts. A layer height of 0.2mm for the frame is important so the plate-facing holes print properly.
2. Prepare the Pi with an OS at the very least, although it's smart to do the full software setup and make sure everything works.
3. Insert nuts into all the recesses in the frame, either by pressing or doing screw pulls.
4. Mount camera module to frame.
5. Mount Pi to frame with the spacer shim under it.
6. Insert nuts into the 2 recesses on the sides of the bottom shell piece.
7. Push I/O shields onto the ports of the Pi.
8. Slide the frame into the bottom shell piece.
9. Wrestle any excess camera cable into submission.
10. Slide the top shell piece on over the frame. The tabs on the sides should line up with the indents on the sides of the bottom piece.
11. Secure the shell pieces together with the countersunk screws.
