I printed it. mounted it on an arrow and got a slight whistle if any noise at all. no disrespect, great design, great print, just little noise :)

Can a nock be made to whistle?

I imagine so; although almost all of the ones I looked into had the whistler piece on the front end of the arrow... I was working on another version that would wrap around the arrow near the end of the nock or just above the tip; however that would require different setting diameter depending on the arrow used (see comment from an earlier ideation)... I also tried an few tests modifying the fletching/vanes in a few ways by cutting or hole-punching but nothing was quite as effective; it's possible that one could build a whistler piece that fits just under the arrow vanes without causing too much imbalance/weight addition to the end of the arrow... an extended knock with the whistle slots/holes built into the hollow portion of the nock might work; you may not need much, take a look at whistler nerf darts and the concept could be applied without creating a large/lengthy piece.

My thinking would be that it'd be way easier to print the nock end and have it not destroy itself :) I might try that if I get really bored one day.

sure thing; I might work on one that mounts under the vanes; it wouldn't be as simple as swapping out a nock though; unless it was one that wrapped around the arrow in a snap fit model...

Presumably this needs to be made of metal to avoid becoming a one-shot wonder?

Could something be designed in plastic that fits on the shaft itself, and is held in place by a target head? I've seen whistling arrows made this way using everything from the little plastic balls in antiperspirant to chunks of buffalo horn. They don't get destroyed too rapidly on impact...

yeah, metal... most of these are turn formed/cast from aluminum or in stainless steel/iron. I've built one before using a simple metal lathe. I did an ABS print on this particular model and the walls are a little thin, if I were to build it with ABS then I will probably remodel it with thicker walls and larger/lonfer cavity. I have seen the ones made from antiperspirant rolls and I might make something along that line next; I was originally trying to build a whistler in two parts that could be attached to an existing arrow shaft a few inches from the arrow tip insert, wrapping around the shaft in two parts; however depending on draw length it could get in the way of the bow shelf or limit full draw. The other issue was depending on how it was fixed (compression fit, screw or glue) to the shaft it had the potential to slide after release or when the arrow hit the target and slide down the length of the shaft towards the vains... thanks for the comments!
