About this 3D model

This is a folk-whistle or penny-whistle, and won't even cost a penny to download. Versions included are sopranino in G, soprano in D, alto in G, and tenor in D (all versions are one octave higher than the corresponding singing voice). The instruments are given as pieces. In ABS plastic they can be welded together using acetone. I have found this method to very reliably produce a functional and well sounding whistle.
