DEDUPEDWho it is forHobbyist who needs a custom case for a Raspberry Pi or similar board
The problemOff-the-shelf cases rarely fit your exact board layout, and mesh editors make small tweaks painful.
The outcomeA parametric case where changing one height value rebuilds the whole part, exported as a printable file.
What you need first
- Windows, macOS or Linux desktop, or just a modern web browser (no install needed)
- Rust toolchain only if building from source
- An MCP-capable agent such as Claude Code only for the agent-driven uses
- No paid keys or accounts
Steps
- Open the desktop app and create a sketch using your board's dimensions as parameters.
- Extrude, then use fillet and shell to form the case walls.
- Pattern standoffs over the mounting holes and cut ports and vents.
- Export as STL or 3MF for your slicer.
Prompt for your agent
Using SolidCraft, walk me through building a case for <board name> with parameters for board length, width and wall thickness, and tell me which export format to use for 3D printing. Verify the wall thickness is a named parameter.
Caveat. The README demo is a Pi 4 case; matching a different board means you must supply its real hole positions and port locations yourself.
About solidcraft
An open-source 3D CAD app written in Rust that agents can drive. Part of this week's top 10 repos: ranked #6 on Repo Radar. View tangency-labs/solidcraft on GitHub.
More with solidcraft
- Let an AI agent model a part you can still edit Steer an agent through the built-in MCP server and get a real parametric model, not a mesh you can't fix.
- Open and re-export STEP, STL and 3MF files Import a model from another tool and export it as STEP, STL, 3MF, glTF or URDF where supported.
- Check how a small assembly moves before building it Combine parts with joints and run a motion study to spot interference before you print or machine anything.
- Design a bent sheet metal bracket and get its flat pattern Use flanges, hems and fold/unfold to model a bracket, then read out the flat pattern for cutting.
- Try parametric 3D CAD in your browser, no install Open the web app, sketch a shape, extrude it and change a dimension to see the model rebuild.
- Watch an agent build a model live in the open app Connect the MCP server to your running SolidCraft window so you can see each modeling step as the agent makes it.
- Generate a STEP file from a JSON command script Run a saved JSON command list from the CLI so the same part can be rebuilt on demand, no GUI.
