Step 1: Materials/Tools
* Heavy paper, such as card stock.
* Thin cardboard, the kind that's not corrugated.
* Double-sided tape. You might be able to use glue, but I haven't tried it.
* X-Acto knife or box cutter. The sharper, the better.
Step 2: Print and Cut Out Pieces
Note: If you're a fancy pants and have access to a laser cutter, this step is essentially moot. I'm pretty sure you could easily modify the .pdf to use on a laser cutter.
Step 3: Assemble the Back and Aperture
Next, stick the back paper piece (the one with the sun-shaped cut-out) onto the cardboard piece. Make sure that they line up nicely.
Now make all the little flaps on the eight skinny pieces stick up. Your fingers will probably be too big to do this themselves, so use either tweezers or the box cutter to fold them up.
Ok, here's the tricky part. Take the one flap with the "A" on it, and put its tabs into the bottom right hole on the back piece of paper. Look at the picture if you're confused. It's very important that this piece is placed correctly, otherwise the logo won't look right. Now, take one of the other skinny pieces, and put its tab into the hole to the left of the previous one. This skinny piece should lay on top of the previous skinny piece. Continue this pattern all the way around the circle, using all eight skinny pieces. The last couple might be a little tricky, since you'll have to get them underneath the "A" piece as well.
Step 4: Close it Up, You're Done!
We're basically out of the woods now. Congratulations! There will be cake and grief counseling at the conclusion of this Instructable.
Put double sided tape on the cardboard piece. You have to be more careful here, because you don't want to get it on the handle piece. What I did was have it hang waaaay off the edge, and cut off the excess. Be careful not to disturb the handle though: it's very irritable.
Now all you need to do is stick the front piece of paper onto the cardboard, making sure they're lined up nicely. You're done! You've been a very good test subject. Please proceed to the next test chamber.
Thanks for reading, hope you enjoy. If you have any ideas on how to make this better/more efficiently, please let me know. Oh, and if anyone is interested in seeing a version that opens the aperture, instead of closing it, let me know in the comments.
