This is V2 of a mechanical Iris Ring Box inspired by something I saw on instagram.
 

For a FULL 3D printed version of this box check out V3 on my page: [https://makerworld.com/en/models/2264530-mechanical-iris-ring-box-v3#profileId-2467826](https://makerworld.com/en/models/2264530-mechanical-iris-ring-box-v3#profileId-2467826) 

However, V2 (this model) is worth the money spent on the bearings and screws. If you're using this for something important get the bearings and do some post processing on the print.

Materials:

• 3 M3x6mm screws
• 6809ZZ Deep Groove Ball Bearings Z2 45mm x 58mm x 7mm. 
• Also 6mm foam or fabric
• Superglue

About ~$10 for the screws and bearings, I had glue and foam.

NOTE: You need to print twelve leaves, so you might have to print the leaf plate twice
