About this 3D model

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. http://www.youtube.com/watch?v=7MuuGTKBjqM&list=UUEQEl_OG8BzNBhR2UyOAjdw&index=1&feature=plcp
