Cam idler pusher for V5 micro extruder.

well i wanted to add spring tensioners to my V5 so i went ahead and added a cam tensioner. Here it is... i am using M4 bolts as spacers to get the springs loaded properly.
UPDATE: 2/3/13
Added a stl for the body with out the follower inside, and one for the follower by it self, plus i uploaded a plate with all 3 pieces (with the cam follower printed out side the body)

the carriage still needs a bit of work before i release it the fan mounting holes are 2mm to close....
