This is a flat base with a GoPro connector to be used as a "monopod" type of camera mount. I printed it with a 1mm nozzle and .8mm layer height (settings from a prior print) just because I wanted it fast. But I really like how that large layer height ended up with the concentric circles on the top of the print. It needs a little cleanup, but that can wait until I am bored some time. LOL

The extension arm in the picture is from Thing 2449620
The camera holder for the C270 webcam is from Thing 1729459

I am including the Fusion 360 file if anyone wants to modify it.
