C270 Mount for Articulating Camera Mount for Mk3 and Mk2

I really like Sneaks' articulating camera arm, but couldn't find a C270 mount for it, so I made one. The outside hole on the mount is 3.6mm to allow a 3mm screw through. The inside hole is 2.8mm so you can just thread the screw into it. An 18mm or 20mm screw should be fine. F3D file included in case someone wants to modify it.
