Logitech C500 Tripod Adapter

I dug out an old Logitech C500 I have to use with [OctoPrint](http://octoprint.org/). An oldy but a goody, the Logitech C500 still has serviceable specs, but there was not a good way to mount it to anything. I designed this small adapter to allow this webcam to mount to a standard camera tripod.

As I generally avoid threading directly into plastic, this design uses a captured hex nut for durability. There is 1/16" of material below the hex nut to ensure sufficient strength during use. The geometry of the inset for the hex nut has very tight tolerances, particularly regarding the height of the hex nut. These tolerances are due to wanting the first layer above the hex nut to print onto it. There is a relief above the hex nut for the screw threads, allowing a total thread depth of about 0.330" (1.5x the thickness of the hex nut). This relief has a domed top to allow the print to be completed without support.

The outer surface of the adapter is knurled to facilitate easy gripping.
