Strong Dog Whistle

A dog whistle designed specifically for 3d printing. STL and Prusaslicer 3MF files are included. I noticed that many other dog whistles on sites such as Thingiverse had a tapered end close to the lanyard hole that would break off very easily when the whistle was dropped. This was the only whistle I tested that survived a 5 metre drop test on to a marble floor. Note that the weakest point on this whistle is the hole where the air comes out. No whistle that I tested survived being thrown up ~20 metres before falling onto concrete-but while all the other whistles I tested broke in multiple places this was the only one that broke into two pieces. FFF 3D Printed dog whistles do not come much stronger than this.
