This magic circle puzzle is published in a book “Creative Puzzles of the World” from 1978. Originally to make from wood.

I adopted it for 3D printing.

The photos above are from a print that is scaled to 50% z and 80% x/y.

I decided to print each segment individually and then glue together in order to avoid support. My profile has an assembled version too, if you prefer this. I did not test that yet.

There are two ways to assemble it (after printing)

a) glue together all pieces in the assembled version

b) glue together the 3 pieces of each part individually. (you may use my optional template/stencil for that)

In case of a) your first task will be to get the 3 parts apart afterwards (see 3 pictures in the assembly guides)

In case of b) you need to put them together.

Have fun finding out how it works.
