Boatswain's Pipe

A working (painfully loud) reproduction of the classic whistle used on ships to pass signals.

Please don't try to smoke with it. It's not that kind of pipe.

Print with 0.25mm layers. Supports not required.
If you want to sand it, it's easier to do so before gluing together.
You will need to glue the halves together with CYA or E6000.
