I'm also self-funding my own solo-dev "in it for the love of the game" agentic app[0], mine for woodworking. It also supports STL output for printing the woodworking designs.

I found building an MCP was the easiest way to avoid paying for inference or having to charge to try it out. Anyone can add the MCP to chatgpt or claude and use their subscription to do the inference.
