ThinkFun the amazing Crankshaft SET !!

thingiverse

This (super amazing) Crankshaft SET may not seem like much.. But can you imagine a train without a crankshaft ? A car without a crankshaft? even a mechanical bird uses one. . DUHH :^) This set will "magically" enable you to convert : Radial motion into Vertical motion ( and visa-versa ). (Machino Geeks , like myself , knows it as " Rotational / reciprocated motion " -look it up) This set is dimensioned to fit the entire thinkFun collection of axles and connectors . So if you like it - please press the "Like" button .. Cheers mates P.S. You can print the "complete Set" file - at once ...instead of each one at a time. update:I've just made a small hole - in case there is a lot of load on the shaft . The 1.8mm hole should accept a standard toothpick - to hold the pin in place. Just insert a wooden toothpick and break it inside.. as shown as tiny green cylinder in the image.
