Description
This music instrument was inspired by kazoo. But it was designed with trumpet shape. Sound is generated by peace of plastic sachet. This membrane size is 40 x 40 mm and optimal thicknes about 0.01 mm. Membrane mounting ring should be melted in hot water if it is too tight. Membrane should be gently tuned with mounting ring. There is no sound when membrane is too taut. Tone color and volume can be modified by covering trumpet with hands. (see https://youtu.be/lApprPbLZr0)
All components are printed alltogether. Brim is needed. I printed it from PLA and PETG filament.
