Train Whistle 4 Tone Remix Single Piece Print No Supports

I loved the fantastic train whistle by 3DVJ (https://www.printables.com/model/456661-choochoo-a-3d-printable-4-tone-train-whistle-v31/comments/840929) but didn't like having to put bits together. So bippity boppity boop, combined into a single printable piece, no assembly required!
