The M2.5 screws now screw directly into the mount/adapter. Be careful about how many times you attach and detach the camera from the mount/adapter. It's not designed for that. Attaching it once should suffice. After that, you risk stripping the threads that you create the first time you screw in the screws. I know there's a way to melt metal pieces into a print so that you're screwing metal screws into metal threads… I've not gotten that far into design… and this fits my needs for now. So, if you know how and want to rework the design, feel free.
Attach the camera module before you attach the Pi. You'll want to connect the camera ribbon to the camera before you attach the Pi as well.
!! WARNING - IMPORTANT !!
- The camera card will NOT be flush with the back side of the mount adapter. Do not overtighten the screws. There's a small gap, so pay attention to the corners as you screw in the screws. If you see them start to bend, just back out the screws a little bit. (Though if you wanted, you could modify the relevant negative space cylinder in the project file so that it's 1 or 2 mm deeper. That would probably do the trick if you wanted it flush.)
Other Considerations:
- I initially used smaller stand-offs between the Pi and the adapter, however I was nervous about the proximity of the backs of the camera and pi cards… I didn't want to accidentally short anything out, so I used the 10mm stand-and that feels safer.
- I also noticed that the Pi still got pretty hot, so this is probably better anyway to prevent some of that heat from affecting the sensor.
- I didn't have spare female to female stand-offs so you'll see in my photos that I've used the male to female stand-offs with small standoffs on the other side of the Pi board to secure it… it's not ideal, but it works.
- Apologies for the supports in the gcode… the supports in the screw holes are a pain to remove. Do so carefully so as not the jam the plastic up in there. I designed this in Prusa Slicer and there's still a bug with stl exports, so I had to basically do all supports or no supports, otherwise I would have left supports out of the screw holes. I'll fix this at some point.
I printed with Prusament ASA, 15% infill.
