About this model

This is a test of my own working Iris from stargate. At first I did not even consider to publish it, but after i published a video about it, i saw that there is a demand so here it is. The iris works, It fully closes and retracts. For the assembly, please take a look at this video where I describe the mechanism. I also uploaded step file of the whole assembly for those of you that need to tweak it little bit and i also added the blade with a thickness of 0,4mm
