Hello ! this is the instruction of the iris hinge assembly for my lasercut iris box.
You can download it on Thingiverse : https://www.thingiverse.com/thing:2704046
For one box, you will need :
- x5 M3 10mm screws,
- x5 M3 12mm screws,
- some wood glue.
In this instructable, i will make a small model for example.
Step 1: Organize the Layers
There are four layers for the hinge :
- The rotating top,
- The petals,
- The rails part,
- The spacers (just here to have a nice length for the screws) .
Step 2: The Petal Hinges
Align and glue the 5 spacers on the holes of the rails part. Screw the 10mm screw in there. There is 4mm of screw that are poking out, it will be used to make the petals pivoting.
Step 3: Fix the Rotating Top
Add the 12mm screws on the curved rails up to the holes of the rotating top. don't screw it entirely, leave some space, so it can slide without be stucked.
Step 4: The Box
Put all the slats on the bottom.
It may be difficult, so be patient. Don't forget not to put glue next to the rails, it could stuck the mechanism.
Well done ! your box is nox finished ! Make sure to open/close your box a few times at the beginning to unstuck it.
