Designed this to mount my OAK-D Lite camera on ceiling for a project I was working on. It uses nuts and bolts from the original Multiboard (and of course the Multiboard itself). The 10mm 1/4"-20 camera mounting screw is from here: https://www.thingiverse.com/thing:2783475

The parts are modular and configurable; e.g. for longer arm with more articulation just print more of the chain link.

And thanks to Multiboard you can use it to mount anything else to the wall, under table, or anywhere you fancy. I've plated together the parts required for the configuration shown in the photos for convenience. You can separate them in your favorite slicer. Also remember that the OAK-D Lite camera can get pretty hot, so print this with more temperature-resistant material like ABS.
