Catalan polyhedron lamp

NYC Resistor installed a Shopbot last year and we’ve experimented with different materials. Today I spent some time testing how well the bot would cut Coroplast. This corrugated plastic is very lightweight, fairly inexpensive, and reasonably rigid when triangulated.

There are some problems with cutting it with a rotary tool like the Shopbot, so I wrote some notes on tooling, speeds, feeds and clamping. There is likely a better way to bevel the edges than the 90 degree bit, so I’m still searching.
