Whistle using v29 chamber profile and rotational extrusion

I wanted an easy to print compact version of the v29 whistle.

Initially I tried another compact version of the whistle but had some trouble printing it cleanly due to various surface details and mesh oddities. Looking more closely at that version revealed a very large number of triangles and lots of mesh errors.

This whistle model was built from a 2d profile extracted from the original v29 and rotationally extruded into a wedge shape. Thus it has a naturally very low number of triangles (~
