Airtripper Quick Release Cam Carrier
This is a carrrier that interfaces with http://www.thingiverse.com/thing:237822 that holds the springs and bolts instead of the rubber hose, for those so inclined. The .stl may have some issues, every time I send it to netfabb it comes back with holes. Maybe someone with more skills and a better program than sketchup can fix it. But you get the idea. Bolt holes are 12.5mm apart and the aitripper itself does not need any modification.
Note - updated by Highcooley to fix the slicing issues in the camshaft. See igf 'Cam 3rd Try " works. Kurt updated the camshaft , this time I think we have it .
