Warnings

NO WARRANTY is provided, and no guarantee that all or any of the parts will fit together. 3D printing is time-consuming and an art at the best of times.

However, if you're stuck or have a question, feel free to open an issue on GitHub, and the worst you'll get is sympathy.

Assembly Notes

Check the Bill of Materials for all of the parts needed, and the project wiki for the build guide with pictures, a text-only copy is included in this repository.
