Mechanical Iris/Aperture fidget toy

A Mechanical iris that opens and closes like a camera aperture . This one requires no additional hardware like screws. I do recommend using some sandpaper on one part.. see the video on assembly. 

It's a fun thing to have on your desk. 

Slice it at 0.2mm layer height. Seems to print without supports. Print 9 copies of the Lotus Blade.
