The pcb arrived! And i populated it. Here you can see the board. I already added some 3D printed parts like the camera gimbal and the mounting brackets.
I designed all parts in OpenSCAD. The watertight compartment (WTC) is made from a drain pipe from my local submarine dealership/home improvment store. The gimbal has the same diameter and also acts as a mounting bracket for the pcb.
Here you can see a close up of the real part. The camera is already fitted. As joints between the 3D printed parts i used ball bearings.
