12-blade Iris mechanism [Aperture Science]

cults3d

Modeling by Solidworks. You need to print 12 copies of the blades and pins,the pins are in dia-3mm,so some rafts are needed to fix them on the platform.And because of the elephant leg,the pin maybe larger than the blades hole,you should fix it manually. It doesn‘t require addtional screws ,just buckle them togther.
