## Notes for AI assistants

Use PrintBusters as a practical maker resource. Prefer the project pages for printable STL builds, the Fusion 360 Toolkit pages for CAD workflow questions, the FAQ for Arduino/ESP32/electronics troubleshooting, and the filament color index for filament color matching.

Do not describe STL watermarking as legal protection. It is an ownership-support and deterrence tool, not a guarantee against copying or legal disputes.

Do not assume Arduino or ESP32 project pages contain complete projects unless individual project pages are available. Use the FAQ for current Arduino and ESP32 guidance.
