This is my 3d model of the 6-Piece "Burr" Puzzle. I got the idea from a puzzle included in the "Brainteaser Box" from Marbles: The Brain Store. It is relatively easy to solve, but takes some practice. I have not included a solution here, but one is easy to find online. For printing, you may want to scale it down.
