Whistle using v29 chamber profile and rotational extrusion

thingiverse

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 (~3000). I'll probably eventually add the openscad file and allow customization of some sort. Print Settings Printer: Monoprice Select Mini Rafts: Doesn't Matter Supports: No Resolution: 0.2mm Infill: 20% Notes: Should print easily on any printer. The most difficult part of the print is the two bridges at the tops of the air exit holes. Those bridges provide the bridging support for the rest of the holes.
