This is the CAD model of the second version of my series of mechanical business cards.  This project has been unusual in that the model has a nearly 1:1 resemblance to the original ideation.  Normally, something changes in scale or aesthetics.  But this is very consistent.  (CLICK ON STILL FOR ANIMATION)

CAD Still

 Prototype parts to follow.

This is the ideation sketch of the second mechanical business card design.  The main feature of interest is the moving pistons.  Newton the Robot is turning a crank as part of the action in this automaton.  The scale will be the came business card size as the first model.  I Expect to prototype in a week or so.  Some of the design is from my candy machines… Not scaled, re-created.
