These 12-sided boxes are made with staves laser-cut with 15-drgree bevels on the stave sides. A jig was used to hold each stave at a 15-degree angle. The height of the jig-stave unit was < 0.5 inches to conform with the Glowforge constraints. The beveling was an attempt to get tighter tolerances between staves. [But box wasn’t designed to hold beer!]
The staves were made of Baltic birch plywood and the inlays stained Baltic birch. There are probably better dimension choices, but these show a proof of concept.
