ZMR250 PZ0420 M mount
The PZ0420 M is to small for the standard ZMR 250 mount. Print this one out and you can screw your camera right to it.
1.25.2015 - Design updated with more clearance for the camera, and made a couple of adjustments to the thickness of some parts. Please Expect some filing to be needed to get exact fitment in the ZMR frame. I left this tight to account for different brands tolerances.
