This is a gadget based on the RC2 Quickplate from Manfrotto and a hotshoe on my SB-900. It allows you to mount a hotshoe device (i.e. a flash) onto any tripod head that accepts the RC2 plate. I've included both the original Rhino 5 files and the STL to print the assembled device. Be careful about the weight of the device you attach-- you don't want the plastic snapping and your flash to come crashing down!
