Adjustable Raspberry Pi Camera mounting solution for Solidoodle 2

I mounted a Raspberry Pi on the back of my Solidoodle 2 (http://www.thingiverse.com/thing:99300 ) and in order to use the Raspberry Pi Camera to see print progress remotely, I modified
http://www.thingiverse.com/thing:192364 to be able to mount the camera to the frame of my printer.

Edit:
Added a shorter 10mm link as well as the original 20mm version.
