Remix of Steam Train Whistle

thingiverse

I tapered the mouthpiece, blanked the top surface and added a lanyard hole. On mine I made for my toddler: - I put his full name and our phone numbers on it in case he gets lost. We keep him within arms reach at all times, but if we get separated and I ever hear a "choo choo" I know he's looking for us. - I seriously doubt he'll put the thing down, so the phone numbers will be with him if someone else locates him first. - Train whistles are slightly less annoying than standard survival whistles! I hope your kids dig it! Make sure there's no holes in your layers or it won't work as advertised. .20 layer height or smaller is probably best. Maybe print it on the side to reduce the need for supports and give the mouthpiece a smoother finish underneath. (4/24/19) added a center hole version since it was hard for him to get both slanted holes in his mouth at once.
