Hand Grip for Canon HV20

This is a hand grip for the Canon HV20. It is that thing that makes this camera perfect for film making using a hand camera - it is that one of the two things that is missing on this great camera.

Unfortunately for you I don't use OpenScad because I like SolidWorks... But feel free to tell me if something is missing or wrong.
