About this 3D model

Bought this (too) cheap webcam from ebay: http://www.ebay.com/itm/320718855923 I wanted to mount it to the printbed so it follows the y-movement of the printer. That should make it possible to easily make some kick-ass time-lapse movies. Already tried to make one without this holder, resulting in this: http://youtu.be/6ivs7SEtD-8
