Quad Lock mount on a RAM 1" ball.

This is a slightly modified version of wpvrtis's thing. I found that on his, the locking tags that hang from the lever broke very easily (even whilst removing support), so I gave the joining edges a fillet (curve) to strengthen them. I also found the lever was a little to flimsy when I printed it in ABS, so I made that 1mm thicker as well. Oh, and I removed about 0.5mm from the mount where the lever tags meet, so they don't get stuck together in printing. No changes affect the use of the mount.

Commonly used as a mount for phone cases.

I printed using ABS, this seemed sufficiently grippy in a standard RAM arm.
