A working and print tested velociraptor resonance chamber prop, for the JP fans, or those, who want to know more about the acoustics of a death whistle, since it is technically that with multiple air vents for different sounds. It will not sound, like the movie prop, and it won1t say Alan, but since I tested it by fans, they said it was close enough for a prop.Credit, where credit is due: The base shape is a model by RadioNuclei95, and the death whistle implementation is based on Printalityco. Although his version basically a shell around a death whistle, which makes it hard(er) to print. In my version it is the organic part of the structure. You get 3 files. The whole model with the chamber in it, which has to be printed with supports, and a helved version right in the mit seam, so the line can be masked away in post processing. In that case, I tested it, supports are not necessary. If you have doubts, I tested this on a bog standard Ender 3 V2 Neo, with the standard 0.4 nozzle, 0.2 layer height, basically default settings and it worked.One more thing: Have fun with it.
