v30 (v29) Whistle - Compact Edition

thingiverse

This is a redesign of Goury's v30 whistle (thing:2783665) which was itself inspired by jzisa's v29 whistle (thing:1179160). After printing the v30, I realised that a big portion of the internal volume did not have any sound-making function - it seemed to be there for aesthetics and to put the keyring hole. It also had some features that are hard to print on FDM printers - namely the curved top (that needs a very low layer height if you want it to come out not looking blocky) and the curved inlet holes (that curl up from overheating unless you print really slowly or you have a really well-tuned profile). I therefore present - the v30 "compact edition". This is a whistle that sounds similar to the v30, but is about a third of the size, and uses 40% less material. Here's a comparison (with 0.2mm layer height and 0.4mm extrusion width): * v29: 13.83 grams * v30: 8.76 grams * v30 Compact Edition: 4.94 grams Details of the changes are listed in the section below. I've attached the .stl file for printing, the source .f3d file for editing in fusion, and .step file for editing in other CAD packages if desired. Released under GNU GPL license same as the original v30 whistle.
