Open CAD design for an enclosure that fits the Exaviz Cruiser carrier board.
This repository holds the mechanical design files for a case for the Cruiser (CM5) carrier board. We're publishing the CAD as the mechanical source of truth so the community can build on it, refine it, and print it.
Full transparency: this is the case assembly we designed (and had built as a metal prototype - the finish was genuinely beautiful), but we never adapted it for 3D printing and never finished validating it. Tolerances, port depths, wall thickness, and mounting all need work before it's ready to print.
Rather than let it sit on a hard drive, we've open-sourced it as-is. See DESIGN_NOTES.md for the full list of known issues, what's good about the design, and concrete starting points.
Contributions are very welcome - if you adapt it into a clean, print-ready model (STL / 3MF), tune tolerances, or improve the design, please open a pull request or an issue. We'd love to fold your work back in and credit you.

- FreeCAD users: open
cad/cruiser-case.FCStddirectly (no unzip needed). - Everyone else: download
cad/cruiser-case-assembly.step.zip, unzip it, and open the.stepfile in any CAD tool that reads STEP (Fusion 360, SolidWorks, Onshape, etc.). STEP is a neutral, widely supported interchange format, so you can import it almost anywhere to remix or export a printable mesh.

- Fork the repo and create a branch.
- Make your changes (CAD edits, print-ready exports, fit notes, photos).
- Open a pull request describing what you changed and, ideally, how it printed.
Issues for fit problems, dimension questions, or design ideas are equally welcome. Start with DESIGN_NOTES.md.
