The U-Box is an open source and modifiable laser cut box that can be assembled with no fasteners and no adhesives by utilizing a universal snap fit that is independent of variable material thickness and laser kerf. Because of the universal snap fit, the box can be cut on any laser cutter anywhere in the world. The box has 4 different versions, and was designed for both transparency and portability.

The U-Box was designed during my time with the TLTL, and is in ~300 classrooms/FabLabs in the world. If interested in creating your own U-Box, please visit its project page.
