My father has a 4Sight Dashcam with only one view lens, pointing forward. He wanted to be able to pivot it so he could swing it around 180 degrees. He used wood and metal for his prototype (which you can see in the upright, unmounted armature) and then did a pencil sketch with the dimensions he envisioned for a 3D plastic print, and asked me to print out the sleeker plastic version, which I first modeled in SketchUp. He will drill the plastic pieces as he did his first prototype and give it articulation with a wing nut and a washer between the pieces. I printed the first piece from the base up, but flipped it because it is a stronger print when done on its side. I am uploading both versions here.
