Simple Mouthpiece 25mm — DIY BY BRAS

Free STL File!
This part is included in the 25mm Modular Flute Bundle

The Simple Mouthpiece 25mm is a blowing mouthpiece designed for the DIY BY BRAS system.

The Simple Mouthpiece 25mm is the entry point of the DIY BY BRAS system. Designed to blow into a single 25mm pipe, it can be combined with sound-producing heads, connectors, and other modular components to build a wide range of flutes and experimental wind instruments.

IMPORTANT:
The actual diameter of 25mm PVC pipes can vary slightly depending on manufacturer and production batch. To ensure compatibility with the widest range of pipes, DIY BY BRAS parts are designed slightly oversized. While our finished instruments are individually adjusted to match our current pipe stock, DIY parts must remain adaptable to many different pipe sources. For optimal performance, an airtight seal is required. Simply wrap transparent adhesive tape around the pipe to create a custom-fit seal before inserting it into the printed part.
