Lead Head 25mm + Blueprints — DIY BY BRAS

This part is included in the 25mm Modular Flute Bundle

The Lead Head 25mm is a sound-producing head designed for the DIY BY BRAS system.

Included: Detailed blueprints and instructions for hole placement, assembly, and tuning, providing everything needed to build complete instruments and explore your own ideas using standard 25mm PVC pipe.

Inspired by the Native American flute and other traditional flute designs from around the world, this head has been specifically developed for 3D printing and modular construction.

It is the central element of the Modular Flute BY BRAS. Designed to produce a soft, compressed tone with low air consumption, it allows multiple flute configurations to remain comfortable and efficient to play, even in double, triple, and modular setups.

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.
