Picture of Make a 3D-printable puzzle ring
This instructable shows you how to use solidworks to create a printable puzzle ring for that special someone in your life.
I've gotten a few comments on this, so I guess I should clarify that the ring assembles to a tight fit through elastic deformation of the printed substrate.

Step 1: Crate a "blank ring"

The first step is to create a ring blank.  Basically a very generic ring.
Create two concentric circles of different size (an annulus), then extrude them.

The inner circle should have the same circumference as the target finger.  This website should help convert from ring size to circumference: http://lovejoyjewelry.com/ringsize.htm

The length for the extrusion is up to you.  I chose .375 inches, just because that's how big another ring I have is.

I feel really stupid asking this but what program did you use to design the ring? CAD?
i was going to ask the same question

greetings, oldmicah
I have attached a video showing the two parts coming together. I hope it clarifies things for you!
The video shows the 2 pieces overlapping at some places. Do you have a physical replica? Would love to see that!
oldmicah is right to question the assembly of this. Currently the rings are impossible to combine. you could design the pieces to slide together from the side and it would be a relatively easy design process change. I like the idea though.

Thank you for the step by step! I'm having a hard visualizing how the two halves slide together. Could you include a photo or a little more description?
