Cap'n Crunch Bo'sun Whistle - Fixed some more

thingiverse

The version at https://www.thingiverse.com/thing:3193749 had some issues triggering warnings when attempting to print it at JLCPCB, some artifacts from 3D scanning, and deep gashes along the mouthpiece. I've cleaned those up to some extent using Blender so that it prints without warning, and I've successfully had JLCPCB print it in resin. I claim no authorship; use my contributions as you would like.
