It's a puzzle box, based on a design by Osanori Yamamoto. It's called Identical Twins. The goal is to fit the two identical pieces inside of the base.

As a bonus, you can also print the Tetrahaedral (triangle shape) to create The Cell puzzle with the same base. Try to get the triangle shape in and out of the base through the small holes.

For a challenge, print the base as one piece. Otherwise, print as two pieces and join with glue. For a challenge, print the Tetrahaedral pointy side up (requires some great cooling). Otherwise, print pointy side down with supports.
