News 2024-03-17: My newest whistle design, a Long Range Dog Whistle at 7,000 Hz. Please download here.  | News 2024-01-21: I designed an ultrasonic dog whistle with an even higher pitch of 23 kHz, which you can download here.  |
Update 2023-03-24:
I've added an even louder, lower-pitched variant and made minor design changes for better printability.
WARNING:
This is an emergency whistle and not a toy! It's extremely loud which can harm the ears, so please protect your ears and don't use it near other people or animals!
Summary:
This keychain compatible emergency whistle is a variant of my big Emergency Whistle - much smaller, but almost as loud as it's big brother.
How to print:
All Slicers:
Use a line width of 0.4 mm and a layer height of 0.2 mm, 5 top layers and 5 bottom layers. Don't use support and don't change the given orientation of the objects.
The whistle requires correct positioning of the Z-seam - it shouldn't be placed in the narrow air passages inside the whistle. The Z-seam should be positioned as shown in the images above (the white dots represent the Z-seam). Use the “Z Seam Alignment: User specified” option in Cura or the "Seam Painting" option in PrusaSlicer to achieve this.
Print slowly (max. 25 mm/s for walls) to achieve sharp edges.
PrusaSlicer
Use default settings and manually paint the z-seam as in the pictures above.
Cura Slicer:
- Wall Line Count: 2
- Extra Infill Wall Count: 1
- Z-Seam Relative: ON
- Z-Seam X: 0
- Z-Seam Y: -50
- Enable Bridge Settings: ON
- Bridge Wall Coasting: 0%
- Bridge Wall Flow: 100%
- Bridge Skin Flow: 70%
- Bridge Has Multiple Layers: OFF
