Train Whistle Mouthpiece - Improved Airflow

Based on the idea of Train Whistle Mouth Piece by MJ, the mouthpiece aims to improve airflow and direct the air to the four whistles from Train Whistle.

Features

• No supports required ✨
• Improved airflow 💨

Print

• Ensure good adhesion: chamfers on the bottom prevent elephant foot, but mean that two traces are all that's holding onto the plate
• Overhangs shouldn't be a problem for most printers:
  • y=15mm
  • y=30mm

Updates

• 2025-01-18 v2: Added supports for dangling overhangs

Based on the idea of MJ's remix, with the goal of being easier and cleaner to print on an FDM printer.
