About this 3D model

The product is based on my son's broken trumpet. Accidentally Inside there is a indonesian traditional whistle made from basic materials bamboo coated with paper. so the idea emerged to reuse it and improve it by redesigning the initial shape that is reshaped with different forms. The initially shaped 3 hole trumpet was changed to 5 earpiece. The prototype was build with PLA. And I hope this "Trustle" can build with safe material for mouth.
