One of my first Laser Cutting Projects, a Puzzle Cube.

Here’s the SVG in case you want to try for yourself. Designed for Medium Maple Plywood Proofgrade. Mine was 3.5mm, but I don’t know how consistent that the Proofgrades are. I’ve designed it with kerf compensation, which took quite a few tries to get right. Again, might not work on your material.

I love it! Thanks so much for the design—can’t wait to try it! If you like wooden puzzles, be sure to search the Free Laser Designs category for Tray Puzzle. There’s a bunch.

Good re-purpose and merger of two very standard concepts.

Very cool and thanks for sharing! We have a bunch of puzzles just outside of our workspace for folks to put together and I think throwing this on the table and not letting them know it’s a 3d puzzle will be a great challenge! See how long it takes a bunch of fancy-pants engineers to figure it out. Yes, I am the office trouble maker…

Made this for my nephew. I painted the wrong sides on a few of them, so he thought all the painted sides faced outwards, when only half of them did. 
He finally figured it out and I got a long glare once he figured it out.
Thanks so much for sharing.

Thanks for responding with feedback. Yeah, half the pieces are inverted showing the inside for… reasons unknown. On my board, it makes half the side one shade and the other side another shade. But that’s probably not a good reason.
Anyway, I too have nieces and nephews, and I solemnly swear that our job is to challenge them!
My next design is a device for not poking someone else in the eyes.

Oh my goodness…that is awesome (and possibly infuriating!) I think I’m going to have to make one! My daughter got a much simpler one made out of erasers last year as a gift from one of her classmates. It kept her quiet for many hours. It’s so very kind of you to share the design!
