A co-worker dropped off a small (key chain version) of this puzzle on my desk. I looked at it and thought with only 7 pieces, this should be a breeze. However, I soon found the puzzle very challenging due to the number of potential wrong solutions and the required order of operation during assembly. Anyway, his version was pretty fragile due to the size, so I thought I would scale it up. My version (3” cubed) was made from a scrap 2×4 and a 3/16” diameter dowel.

Very nice! What method did you use to cut the irregular shapes? I’d love to know more about your technique!

Thanks. I used a band saw by hand to cut the notches. Unfortunately, I missed on the accuracy and had to enlarge a few of the holes.
