A burr puzzle, also known as an interlocking puzzle, consists of notched pieces of wood, plastic or metal that when put together creates a three-dimensional shape. This wood version is pretty simple and therefore relatively easy to make. It consists of 12 pieces of which 11 of are identical. The 12th piece is the similar except that it has a notch cut into the top surface which is the key to the solution.

I like the red one best. Never saw one where there were that many duplicate pieces. Usually six different of six.
Did this start out as metric? Some odd dimensions.

Thanks. No, it didn’t start out as metric – just me being weird :). Actually, I started out with 11/16” wood from my scrap pile. The groove is 1/2 of that thickness. When working out the dimensions, I assumed a 0.01” gap between mating surfaces. I used digital calipers for the measurements so it didn’t really matter one way or the other. Attached are more “normal” dimensions for 3/4” wood.

Wooden puzzles are an important part of many cultures!
This one is a classic and well done!
