Ocarina Totoro

thingiverse

This Totoro-phone is actually an ocarina and we can play the theme song of "The Neighbor Totoro". You can access the playing instructions by checking out the screen capture image. The instrument has four holes, and the bottom part of the image shows the finger configurations for open and close positions on each hole. This model should work with most FDM/SLA printers. To print the shape correctly, cut it in half along the original printing direction to avoid damaging the wedge in the fipple when removing support material. We designed this ocarina using "PrinTone," a software we developed. With PrinTone, users can convert any shape into a wind musical instrument. The software interactively predicts the tone of the instrument as it adjusts the size and location of finger holes and mouthpiece. It's equipped with accurate acoustic simulation and can optimize hole sizes to achieve target tones. Check out our project page for more information!
