Super-mini CARABINER WHISTLE for your zipper! Quick print!
Description
A super-mini but surprisingly loud whistle you can put to the zipper of your jacket, a keyring, a backpack...! Print a few of them and give them to your friends as emergency whistle. :-) 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.
