Description
A super-mini but surprisingly loud whistle for your keyring! Print a few of them and give them to your friends as emergency whistle. ❤
Only 5min print time with Prusa MK4/MK4s or Core One (other printers maybe take longer time)
This is also a perfect test-print for calibration of your printer.
Make sure you set the correct perimeter speed (=25 - see below) otherwise the whistle may not work correctly.
