This ancient style of puzzle dates back possibly farther than any documented history of it, and is one of the oldest styles of three-dimensional puzzles we know of. An assembled burr puzzle uses six sticks of nearly-identical shape, the unique notches of each burr interlocking in a way that's hidden when the puzzle is fully assembled.

What makes this set of 25 burrs extra challenging is that, theoretically, you can pick any six burrs at random and usually find a way to interlock them together.

This set makes the perfect gift for yourself or any other avid puzzler; it comes complete with a sturdy black box that snugly houses all 25 burrs to prevent any from getting lost. Buy multiple sets to mix and match colors between them! Just make sure that the burrs you swap between sets are the same pattern.

Each burr piece is 1/2" x 1/2" x 1 1/2" (12mm x 12mm x 36mm).

Brim recommended for the lid; pieces don't need it. No supports necessary.

Burr set design is remixed from Jamie Taylor on Printables and the box is my own design.

Don't want to print your own burr set and would rather buy a pre-made version? I have the pre-made sets available here.
