Printable Interlocking Puzzle #1

This is my brand new interlocking puzzle design that should print perfectly on a well tuned printer. It consists of three pieces and makes a 3x3x3 cube. It isn't too difficult to solve but is the first design that is both interlocking and fully printable without support.

If you like this puzzle and fancy an extra challenge, perhaps you would consider purchasing my latest and best design from here https://pinshape.com/items/42609-3d-printed-printable-interlocking-puzzle-4-level-11-by-richgain
