I had an old c250 rolling around and I couldn't find a mount i liked for any of the sphere style Logitech cams. Only one that came close was https://www.thingiverse.com/thing:3075788. but i wanted to remove the oem stand bit to have a more solid mount, so I made this thing.
Installation: take out the rubber plug on one side of the cam there's a screw under it, unscrew it. Note which way the oem mount is then take it out. Put in this one in the same orientation.
It's easier to print them and glue the 2 parts together. Maybe I'll make a one piece model if i get a chance. Other peeps might find the cam side of it useful for other things too.
may need supports for the cam side part.
