Turbine Whistle - Click fit mounted - No Glue

thingiverse

I just took Turbine Whistle by bakefy and remixed it to avoid glues altogether, making it suitable for kids - no cyanoacrylate in contact with their mouths. I printed it with a 0.2mm layer thickness using an Ender 3 and 30% infill settings, which worked out fine, but you can adjust both configurations as needed. Once printed, place the turbine on its axis and give it some strong turns by hand to soften it up, just like in the video at https://youtu.be/6Avlz_fYlqY. Then add the cover and press down firmly until the click fits snugly into place. You can also add a small amount of child-friendly oil, such as olive oil, to make it turn more smoothly - check out the sound here https://youtu.be/hOBrsjwXxII. I'm still learning 3D design, so this project isn't perfect, but it works for me and hopefully will for you too.
