Powershot to DSLR mount

There were several designs for a point and shoot to DSLR tripod, but none that I found allowed access to the battery and memory card while the camera was mounted. I solved the problem with this design. Memory card and battery access without taking the camera off the mount every time.

EDIT: The screw needed to mount the camera is
1/4"-20 x 1-3/4" long.
