1/4 Inch Tripod Nut

This isn't really a remix of the Raspberry Pi Camera Case and Mount for Mini Kossel by @kevinlo. It's simply a printable nut for connecting the Pi camera tripod back to a tripod screw. @kevinlo's model requires a "real" nut, but I'd prefer to stick to plastic. :-)

The nut is threaded correctly and should easily screw onto a tripod.
