I’m having way too much fun with the amaziograph app and fake geometry in AI (“fake” because I do it visually to avoid using up all my maths). Centered, symmetrical shapes are great in the glowforge, because it is just so easy to flip the shape in place for engraving the back.

Assembled in AI. The centerline stroke shows the vector paths I started with. I put a 3pt stroke on it and expanded that stroke to make the cut. Watching the glow of the laser through 0.04" of plywood is neat; I kept expecting it to burst through, but it never did.
