Anywhere in public is great. If you're in a place where ICE is less active, you'll want to package the whistles with instructions to alert the local rapid response hotline.
I've seen whistles with the number for the local rapid response hotline printed right on them. Must have been one of those fancy multi-filament printers.
Do you have to prime 3d printed objects? If not, just print the number and like dip into water paint. Ideally you could print a lip with higher numbers so only the top of the numbers get painted
Black marker works on most plastic
Only issue with black marker on 3d prints specifically is the ink tends to wick around the layer lines. Still works but doesnt look great. Paint markers are usually my goto
Good enough is good enough
Yup this issue you can see in my picture. I was hoping paint markers would have been viscous enough to not bleed but it did anyways. Not that big of a deal for a fire and forget box of whistles.
