OctoPi and Pi camera holder

raspi_base, port2, port3 and port4 are sticked together, allowing to solder threaded inserts into port3 holes to screw big Pi there, and have camera on top of 30cm high holder hold by soldering third hand 5mm diameter clamp as in initial photo.

Today I printed flat_holder to replace soldering third hand clamp completely, so 100% 3Dprinted now.

3rd photo shows 640×480 Pi camera scene view. Unrelated to this model, you can see borescope nozzle camera in holder superglued to MINI+ extruder carriage. Its nozzle camera view can be seen in OctoPrint as well. I had to connect small USB port hub to Pi3A+ single USB port in order to connect both. Here is borescope holder model:

Last two photos show scene view in dark room (only borescope light on), with OctoPrint torch off and on.

I flashed OctoPi OS onto the Pi3A+ SD card (with rpi-imager) since that does all needed OctoPrint installation+configuration.
