PROTEST Whistles are two-note whistles designed specifically for protesters. Their sound is sharp, resonant, and loud, enabling easy location of group members in chaotic protest environments.

Each whistle features unique words or symbols and can be customized using 3D modeling tools. Several designs are included in the set, along with a blank whistle for personal messages.

Why Whistles? They serve as a warning tool against agents and are effective during protests. Every 3D printer owner can contribute by making whistles for local organizations.

Design and Printing: Whistles are printed on their side to achieve the best sound quality. Recommended settings include a resolution of 0.15-0.16 and an infill of 15-20%. Use whistles responsibly, as they can reach volumes of up to 120 dB.
