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.
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. During our group laser characterization, we found the cardboard to be 0.17", the kerf to be about 0.1", and that it was beneficial to compress the cardboard in joinery by another 0.1". The other parameters control geometry.

Cutting proceeded smoothly. Some of the connectors (and one of the tiles) ended up with critical geometry inbetween corrugations, making them unusably weak.

Here are two constructions.

The extra degree of freedom (from using slots instead of tabs) allows more than two tiles to meet at an edge.
