ThinkFun the amazing Crankshaft SET !! by kola_machina

Last crawled date: 3 years ago

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.
