Design Notes

This fan shroud is specifically designed for the ESP32-S3 development board, accommodating a standard 40mm × 40mm cooling fan.

Features

  • Snap-fit Design: No screws needed — clips directly onto the dev board
  • Optimized Airflow: Simulated duct design effectively covers the main SoC area
  • Great Compatibility: Does not block GPIO headers or interfere with wiring
  • Print-friendly: No supports needed, works well at 0.2mm layer height
  • PLA or PETG recommended
  • 20% infill is sufficient; increase to 40% for extra strength
  • 0.2mm layer height works well; 0.16mm for smoother surfaces
