Raspberry Pi Zero IR Camera 3D printer mount

Remixed the original model, to make it mountable on an aluminium extrusion bar with T nuts. I'm using it for the RPi Zero 2W running Klipper while framing the printer bed with the IR Camera.

I have made some slight changes to the enclosure to make it easier to print and allow the usage of the data USB port.

The base piece has been modified to minimize the profile, and include M3 holes to secure it to the printer.

Finally, I redesigned the lid to be compatible with a different unofficial IR Camera, that is slighhtly wider and has an additional photoresistor on the main camera PCB; the lid from the original model is still compatible, if you have a different IR Camera.

Update Rev. 1.1:

• The original, non ventilated model was running way too hot, with the raspberry ofter reaching 80 °C; I have added a new main box model, with ventilation holes on the back, that hopefully improves the thermals while avoiding the need for active cooling
  
• Revisited the main box model with fan holes:
  
  • Increased the size of the fan holes to allow of more airflow
  • added a channel for the fan cables
  • Added pockets for the screw heads
  • To mount the fans, use M3x18 screws with button heads; the head goes inside the case under the Raspberry Pi, and nuts outside, securing the fans

• Base:
  • Moved the connection arm slightly to the side, to make space for the USB connection
  • Moved the connection arm to the same plane of the bottom of the box, to remove the need of supports
  • Increassed the size of the window for the USB connectors to allow the usage of the second port; added a slight pocket surrounding it to make it easier to connect USB cables
  • Added a second model with holes for two 20mm fans for cooling
  • Added a third model with ventilation holes on the back
• Lid:
  • redrawn the IR camera cutout to ensure compatibility with the IR Cameras I have; they are slightly wider, and have an additional photoresistor on the main camera body
• Base:
  • Narrowed the base to 20 mm, to prevent interferences with the mechanical assembly
  • Added added holes to secure the base with M3 screws to T nuts
