Puppy (http://www.thingiverse.com/thing:1087797) I modified and redesigned these characters. I combined two ( a character and a whistle) into a character whistle by using Autodesk Meshmixer(http://www.123dapp.com/meshmixer). Each whistle has 2 different mouthpieces (with one hole and two holes, respectively). The mouthpiece with two holes creates a higher frequency (pitch) sound. Each character whistle can produce about 90 decibel sound. So, you can also use it as an emergency whistle for natural disaster situations, crime prevention and scare animals. Choose a character whistle you love, print it, and blow it! Print Settings Rafts: Doesn't Matter Supports: Doesn't Matter Resolution: 0.2 mm layer thickness Infill: 25% ~30%
