Modular Flute Bundle 25mm — DIY BY BRAS 

All components included in this bundle are also available individually as STL files and physical parts.

The Modular Flute Bundle 25mm is the complete bundle  to build all the Modular Flute models.

Designed around standard 25mm PVC pipe and interchangeable 3D-printed components, it provides everything needed to build simple flutes, double flutes, triple flutes, drone flutes, and a wide variety of experimental wind instruments.

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.

The bundle brings together the core building blocks of the system: Lead Heads, Drone Heads, Mouthpieces, Double Rings, and Sleeve Connectors. These parts can be freely combined, modified, and reconfigured to explore countless instrument designs.

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.
