Hello Lorenzo,
I'm a preschool music teacher trying to experiment with my teaching methods. Do you think I could use Tinkercad and Doodle3D for 3D printing in preschool music education? I've been looking for examples of Tangible Interfaces in the 3D printing classroom. I thought I could start with non-idiophone musical instruments and their parts (like hovalin or a simple mouthpiece design from pimion labs) to explain how they work in practice.
