## Laser Cut Construction Kit
One of the assignments this week is to make a parametric cardboard construction kit on a laser cutter. I like platonic solids, so I'm going to base my kit on a dodecahedron. I sketched these tiles and connectors in Fusion 360.

For fit, there are three main parameters: thickness, kerf, and epsilon. Thickness and kerf are used to make shapes that should exactly interlock, and epsilon determines how much I intentionally undersize certain components in order to compress the cardboard. The other parameters control geometry.
