This is a proof of concept of a printable two-way clutch. Feel free to improve/remix this idea.

The clutch is freewheeling when the lever is not engaged. When the lever is engaged, it drives the output gear in the same direction as the lever. For shaft, I just use a 5mm hex key. 

There is one problem I have not solved yet: when the lever is released the output shaft often rotates back with the lever to its original position - I just squeeze the shaft with my fingers, so there is some friction that prevents it.

No support needed. Printed with PLA.
