About this 3D model

Added a louder and easier to print version 2 (V2) whistle. Slim 7mm thick keychain whistle prints in about 14.5 minutes. My Print Settings: 1st layer 0.25 layer height: * 0.10mm * layer height is critical for proper rattle separation. I use X-ACTO knife blade to loosen the rattle. Printed with my favorite PLA+ filament https://numakers.com/?ref=tQdUqtxM So, how does it sound?
