Micro Emergency Whistle

Dual tone micro emergency whistle that takes less than 3g and a few minutes to print, yet can easily reach over 100 dBA! There is a smaller one already on MakerWorld, but for the exta 6mm you get a second tone and over 20dBA! I made these specifically to be used in these models: Discrete Emergency Whistle Pendant: https://makerworld.com/en/models/1535011 Discrete Emergency Whistle Cross: https://makerworld.com/en/models/1535085 Scaling tested pretty good between 85 to 120%, but 110% was set to default for reliablity and shrieking sound. Printed dimensions are aprox 1.4" x 0.25" x 0.30" (46mm x 6mm x 6.6mm.) Jump rings between 8 and 14mm will work, along with 0.5 and 1 inch split rings. For optional custom text, as pictured in gif above, chose a custom text print profile, open in Bambu Studio. Switch to object mode, Right Click on Right Click Here and select Edit Text. Delete “Custom Text” and enter your choice of new text. Changing Fonts/Size is not recommended as very few
