    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.

      You can do it with any 3D printer, as long as you orient the letters so they’re at the top of the print, you can insert a pause in the print job just before it starts the layers with the letters. Then you do a manual filament swap and resume the print.

      Another option is to print a QR code on them with a link to instructions/the organization.

      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
