3d design files for sts camera mount

I have a couple of sts-pis and find that the camera mount is too low. The view from the camera is 1/2 floor. Does anyone have a 3d design of the camera mount. I want to modify it so that it is about 5cm taller or on a 30 degree angle.

If taller, maybe I could add an ultrasonic sensor to the front.

Thanx
