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
