Summary

I wanted an iris that I could control with an arduino or a raspberry for a project. I haven't found anything to my liking but I had downloaded this iris for fun a while ago and knew it was a good quality one.

So I've decided to remix it to include a support plate for a standard 120mm computer case fan and a rack to be able to turn it with any kind a motor.

I'm aware the rack on the rotor is way too long so most teeth aren't doing anything, but I just didn't want to bother to find the exact travel length of the rotor so.. sorry for the few milligrams of wasted filament. But it looks good !

I'm putting back the original leaves and pins here, but all credits goes to jbergmans for this wonderful iris !

All the instructions to put it together are on the original page, go check it out and give him some love !

Tip for a smooth travel

I've noticed it kinda get stuck on it's own, probably my ender3 being not 100% accurate.

So I've sanded everything with 420 sandpaper, applied some WD40, and made a very janky setup with an arduino and a 23BYJ-48 5volts Step Motor.

I'm gonna provide a .ino file for a very simple back and forth movement with the appropriate gear that I used. I just ran it overnight and the next day it was going very smoothly and without any issue, hopefully it'll help you.

You shouldn't change anything on the ino file but I've still commented if you want to use it for something else or if you are not using the same step motor
