Bat-Whistle
thingiverse
On a recent trail run a couple people got separated from the group. Nobody was lost for long and we ended the run with some laughs and jokes about needing survival whistles... which is actually a good idea. Since our club is called the BATS I remixed this whistle with the club logo to make complimentary Bat-Whistles! Post-Printing Minor filing (or just poking around with a paper clip) may be needed to clear out the airway of any stray filament for a clean sound. How I Designed This Opened our club logo SVG in Inkscape. Selected the "bat" shape. Used the Paths to OpenSCAD extension to export the path to an extruded polygon. Edited the OpenSCAD file directly to import and superimpose the whistle model.
With this file you will be able to print Bat-Whistle with your 3D printer. Click on the button and save the file on your computer to work, edit or customize your design. You can also find more 3D designs for printers on Bat-Whistle.
