A first pass attempt at printing the frame of a small, toy, rubber-band powered flapping flying machine. This small ornithopter is based on the tutorials I've seen for wooden ornithopters on Instructables, most particularly on the tutorial by Captain Molo

Known Issues
Please note, this is WIP - mostly because I couldn't get it to reliably fly. It prints - it assembles - it flaps in your hands. But when I try to fly it, it manages only a few flaps before stalling.
I suspect that wobbly axles are losing me most of the rubber-band power, but it could be anything at this point.
I also suspect that massive weight savings could be made on future iterations of this ornithopter - the one I've uploaded here is SOLID. There is no flex, even when it's crashing nose first into the grass. There's fat to be trimmed here, for certain.
