Hi, this is my instructable for the "Ring Challenge". It's something I invented a while back. I called it the "Ring-Box Ring". It's the only ring box that will allow you to display your ring directly where it belongs (on her finger), without spoiling the surprise. It's shaped like a ring and it opens once the real ring inside reached it's target.

Step 1: Making the Original Shape

I used cardboard 1 mm thick. I cut it with an x-acto knife and glued it together with wood glue. I didn't used any patterns at first, my only concern being the dimension of the hole. You want the box hole to be the same size as the ring's hole. We'll assume that the ring is the right size. (In all the movies I saw it was). The rings come in various shapes and sizes so I thought that's going to be a real problem for mass production. In the mean time 3d printers came along making it easy to produce anything you can think of, with a push of a button.

Step 2: Making the Silicone Mold

The box is made of two parts. It was extremely easy to make the silicone mold for the small part of the "Ring-Box Ring". For the big part I made the mold in two layers with a small hole on top for pouring the resin.

Step 3: Resin Casting

Having the molds prepared, I used polyurethane resin for making the actual boxes. In the end they were light, easy to sand and very, very resistant.

Step 4: "Ring-Box Ring" in Action

Here you can see the "Ring-Box Ring" in action. I thoutht it's a great idea so I tryed to sell it, of course, but didn't have much of a success. Jewelry box producers weren't interested in any new ideas. Maybe they thought their products can't get any better. In the end I decided to share it with you guys. Make your own, have fun, but never try to sell it as your own idea. It brings bad luck! Please share this instructable.
