Make your own

Snapwright is a free skill for Claude Code. It designs a brick model from a photo or an idea, checks that it holds together, and gives you a link that opens it here.

Then ask Claude: "Design a brick model of my dog and open it in Handbuild." Star Snapwright on GitHub if you like it.
