About this 3D model

Mechanical AND logic gate *** WORK IN PROGRESS *** http://www.youtube.com/watch?v=DUVhZNWdc1s&list=UUg-5QuUzIRufp14aasHsBvg&index=1 I could not find a usable mechanical AND gate on the internet, so I decided to make one. It was important to me that the design was clockless and could actually work in the real world. this is my first attempt. I hope to improve on this design. The current model generally works, but can stick from time to time. it also needs to be cycled for about 5-20 minutes to loosen up the parts after you first print it Printed with replicator 2, 0.3mm PLA Extra Parts 2 small springs (from mechanical pens ) 1 rubber band
