Description

Some weeks ago i found chris schaie's [1] iris on hackaday [2] and i was so amazed that i took a screenshot from the video and made my own iris based upon his design.
From there it was a long road but eventually my own design worked out and i managed to create a mechanical iris that can be opened with a stepper motor.
Now we have a welcoming system at the metalab [3]

Instructions

Documentation can be found @ metalab.at/wiki/iris

To build the thing you need
- a lasercutter
- wood (i used 8mm)
- 3 ball bearings from rollerblades
- a stepper motor + controller electronics

kind of looks like a modified version of the .dxf file he uploaded to the forum, i made a mini version a while back based on his original (and flawed) design, hence the reason the iris doesnt close perfectly. I was working on a larger one but my lasers co2 cartridge started running low an ended up wasting alot of plastic before i realized it was dieng

this design is based on a screenshot i took from shaies iris, as mentioned above.

the whole design was then started from there.

when i was finished i found out about the talkshopbot forum and contacted chris.

the design then evolved a little more (the iris closes without gaps) but at no point i took any of the existing .dxf files. of course i asked chris if he was ok with me releasing my design here and he was fine with that as long as he was mentioned.
