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.
Heat stamping might be quickest alternative. Should be rugged and aid low-vision use.
Full brass letterpress type sets and die can be pricy, but the cheap leather iron kits at craft shops commonly include small metal alphanumeric types that could be set (clamped) and affixed to your stamp (burning/soldering iron or pliers + hot plate/stove).
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
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
If it’s bevelled text you can swap filament during print to make it stand out / easy to read.
Only problem is that you have to baby sit the print, which could slow down production considerably
Been printing them, just need some good locations to place my boxes
Which STL do you prefer?
