T-Slot Camera Stand

This is a version of my [Universal Camera/Phone Stand](http://www.thingiverse.com/thing:1128880) that is suitable for larger cameras such as DSLR and video cameras. It incorporates a T-slot that holds a bolt which attaches the camera using the tripod mounting hole. The t-slot allows the camera to be positioned in a stable position irrespective of the camera's centre of gravity.

The range of positions is limited to +/-45deg roll and pitch in 11.25deg intervals.
