3-Plane Connection

One of the problems given in a digital fabrication class I took at MIT, Course 4.592 – Research in Digital Fabrication with Prof. Larry Sass, was to design, fabricate, and assemble a joint that could resolve the intersection of three orthogonal planes, using only sheet material, a 2-axis laser-cutter, and friction to hold the assembly together (no fasteners or adhesives were allowed). My partner on the project (Si Li, SMArchS ’08) and I designed this joint which met all of the design requirements and reduced the number of unique parts to only three.
