Moving RaspberryPi camera at 2020 alu delta tower

thingiverse

When I print tall things on my delta printer, the effector/nozzle left the viewing area of the camera. I made this Raspberry Pi Camera holder, which clamps lose on one delta tower and moves with the print head, lifted by a carriage on the linear rail. This allows a good view on the nozzle and the previous printed layers, no matter how tall the object is. I made a video, to show the idea and the resulting view of the Raspberry Pi Camera: <iframe width="560" height="315" src="https://www.youtube.com/embed/m5rbVdU5Nuc" frameborder="0" allow="autoplay; encrypted-media" allowfullscreen></iframe> Another video with time lapse view only: <iframe width="560" height="315" src="https://www.youtube.com/embed/8meXmRKXBJs" frameborder="0" allow="autoplay; encrypted-media" allowfullscreen></iframe> (A few months ago I saw a similar idea somewhere on Youtube, but I can not find it anymore.
