iSight mount for M2

This iSight mount depends on my 80mm fan mount (http://www.thingiverse.com/thing:250254), so will only be useful to that vanishingly small population of people who a) own an M2, b) want to relocate their bed fan, and c) have a hundred year old Firewire camera. Still, the general idea of using the right side of the M2 by clamping things to the rail may be useful to somebody.
