My dad and I designed this 3d printed Puzzle Box and thought it was fun to mess with.

does require some assembly using super glue or something as good

to do this just place the glue in the divot of the pin and attach it to the square piece while the square piece is INSIDE the puzzle

just drop the pin with glue on top of the square

do this for all of the pins, place something inside, put the lid on, shake it up, and have fun trying to solve it, or have someone else try to solve it!
