Double Ring 25-16mm — DIY BY BRAS

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

The Double Ring 25-16mm is a structural ring designed for the DIY BY BRAS system.

Designed to hold one 25mm pipe and one 16mm pipe together, it provides alignment and stability while maintaining the standard spacing used throughout the DIY BY BRAS system.

IMPORTANT:
The actual diameter of 25mm and 16mm PVC pipes can vary slightly depending on the manufacturer and production batch. Unlike airtight components such as heads and connectors, the Double Ring does not require a sealed connection. Its open design accommodates these small diameter variations, making it compatible with a wide range of 25mm pipes from different sources.
