These keychains are realistic models of the first atomic bombs used by the United States in WWII, Fat Man and Little Boy. There's two options for printing Little Boy – to scale with Fat Man (which is a tad tiny) and then enlarged to be similar to Fat Man – your choice :-). There's also two options for the size of the hole, Large to fit a traditional key ring, and Small to fit a keychain (like you see in the model photo). No assembly is required, just print in place and then attach to your key ring or keychain. If there's other military equipment you'd like to see as keychains, let me know in the comments and maybe I can make it happen :-) If you're looking for the bigger models you saw in the model photo, here's both:Fat ManLittle Boy Bambu Filaments used are:Fat ManMatte Latte BrownMatte BlackLittle BoyMatte Dark Green
