Blackmagic Design Micro Converter Mount
thingiverse
I felt really cheap and didn't want to pay $13 USD for a converter mount. This took me about an hour to print and the only thing it cost me was time. Ya know, that thing you can't get back. You'll need a couple of longer M3 screws to replace the ones that are screwed into the converter. Then you just need a magic arm or friction arm to mount to your camera cage. The middle thread is 1/4-20 so it would fit any standard camera mount, unless you have a 3/16 mount in which case I cant help :)
