I was able to quickly create a design for my ENGR 100 class and then cut the pieces with the Shapiro Lab's Glowforge Laser cutter. I made the box design for cutting myself, and the engravings are designs from the web.
Cutting the pieces takes only a fraction of the time it would take to 3D print the design, and the pieces fit together perfectly the first time. And while the design isn't complete yet, I can easily come back with any revisions and re-cut the pieces.
