Reciprocating Piston
thingiverse
I tried using a piston instead of just a rod on my first build, and it worked out a lot better - I got much smoother movement. You can see an animation of it in action at http://youtu.be/FjwK4FDGRek. \n\n Instructions:\nJust attach the shaft through the piston hole and connect to the pin connector, then snap on the end caps.
