Raspberry Pi Zero HQ Camera attachment for short cable

I had the short (3.5 cm) Pi Zero camera cable which fits nicely onto the original mount when using M2.5 spacers but I didn't have long enough M2.5 screws to mount the camera with nuts.

I re-drew the design such that the screws can directly cut into the plastic without requiring nuts. I also re-aligned the Pi's position such that the camera cable attaches straight.

There are two versions:
- the same layout as the original but with aligned camera port and smaller screw holes
- modified layout such that the camera cable stays clear of the HQ Camera's tripod mount
