*IMPORTANT*
You must turn down the stepper current for your z axis motor before using this coupling (if you print it in pla). On the standard one/two-up, the stepper currents are set too high by default and as a result, the steppers get very hot. This can actually allow the coupler to deform enough to become unusable, so be sure you turn down the current!
Here is a flexible coupling I designed for my two-up 3d printer. It's design allows it to be printed relatively quickly, it has suppor
