About this model

This is an iris mechanism built into a business card sized card. For simplicity and to help keep the thickness low it only has 3 leafs. This particular design does not scale well to more leafs unless it is made much larger. The initial design did have 4 leafs and is built in a way that would allow it to scale to a different number of leafs more easily. If anyone is interested I could upload that as well.
