5 Point Iris

A second mechanism for Vale LRP and another file that has been floating round the internet. This Iris is a neat piece of engineering that has been built by dozens of people. I rejigged it slightly to put some better gears around the outside but other than that it's the same. Instead of using nuts and bolts to hold it all together it is all made from wooden parts, each pivot point is made from a 6mm wooden dowel. (svg here)
