Description
Edit I: Design has been modified to increase the clearance between moving parts. I've also centered and oriented the parts in better positions for printing.
Edit II: Design files posted. DXF, STEP and the original CATpart for those with access to Catia. Thanks to everyone for your photos, videos and design feedback!
Edit III: Be sure to check out Jon Hodgins' version: thingiverse.com/thing:5589

This is very cool, but very big too :) Unfortunately, I underestimated it's size (85mm diameter for the base ring). And, my Mendel Z got hung up at the 80% mark so it's a fail for me :(. And that was 8 hours later (skeinforge predicted 5.5 hours). Will try again when I get some more PLA :)
As a consolation I now have a very cool looking pencil cup 8-)
Nice to see other people using CATIA, but why's it done using a CATpart? Would've expected an assembly...
Having some trouble printing out the geared part of the shutters. It just gets real blobbly. Any tips?
Hmm.. maybe integrate a sliding lock to keep it closed
Originally I tried to get the tolerances close enough so friction held it open or closed. If nothing else you can tighten down the screw a little till there is enough drag to keep it from falling open. Can anyone who's printed the latest version comment on how well it stays closed?
How long did this take to print for those who have printed it.
I have the shutters printed, and I am currently mid build of the base, which has been printing for 2.5 hrs and has 4 hrs left. on a printer that only has about 30 hrs of total run time on it. Im hoping to have it all finished by late tonight.
I scaled it down to about 3/4 actual size, the projected print time unscaled was way too long for me to wait for. I have an estimated time of 2 hours and 50 minutes for the base. Already half way through that. Streaming it live on ustream as we speak. I hope my motors can hang on for that long (been having some overheating issues, can def cook an egg on my x and y motors).
here is a link if anyone cares to view.

I did but my printer supports overhangs. It just uses a lot of plastic so I flipped it for conservation of materials.
msruggles... Do you think you could upload the dxf or skp etc? Files that you made this in? I am going to take a go at creating a laser version.

The ring was a little tight around the base I didn't have to do anything to the holes but I didn't use an m3 screw either. I used a 1/8 3 inch long bolts for drywall anchors.
After a lot of sanding I was able to get this assembled and working. I'll post a video tomorrow.
It's just a bit too tight to work when fully assembled. Everything fits together fine but it's too difficult to turn after the 3rd shutter is inserted. Reduce the diameter of the shutter stem by a tiny amount and it should work. Also your gears are a bit tight but fixing the diameter of the shutter stem should be enough to fix it. Great job btw. Looking forward to getting it put together and working.

Hi again! I'm having trouble printing the ring on my afinia. It crashes the build software. Is there a way you could send me the file in a format I can open with blender or meshlab(.obj, ply, etc)?
Sorry mate. I lost access to CATIA some time ago so there isn't much I can do for different file formats.
