Description
A simple and compact overrunning clutch or freewheel. See the Wikipedia page for an explanation of what it is and what it can do. If you ever wondered (when riding a bike) why the pedals stop rotating as soon as you stop pedaling, this magnificent device is the reason why. It basically is a mechanical diode.
After printing clutch.stl, you want to move the two fingers around carefully, little bit up, little bit down, little bit left and right until they start moving around smoothly.
And yes, a single finger would have been sufficient. Consider the second finger a hot backup.
Use a few drops of glue to glue the covers to the clutch.
Only the ratchet needs supports.
