Post-Printing

You'll need to print 5x of the pins, press them into the left most hole when you have the leafs pointing down. The right most hole goes on the pegs on the front cover. Then just slip on the back cover, and twist it clockwise and counter clockwise to open and close the iris.

How I Designed This

This is just a part of a mechanism I designed to cover a IR target used in an arcade game. I initially designed it in SolidEdge 2D Drafting, then imported it into Rhinoceros 3D
