I'm naming my little 8 inch ones "Tacticals" as a nuclear weapon joke lol. I need to empty a beer bottle or two to make a replica of the ones in the game.
I'm planning on doing more but i have my plate so full now lol. I'm slowly getting parts for a life sized robobrain. Sadly the brains show in the robots are WAY bigger than human brains despite them being taken from prisoners before the war so i guess mine will be real world accurate lol.
I don't know if anybody's still interested in making Nuka-Cola bottle caps or not, but there's a company called Crafty Caps that already has a Nuka-Cola logo uploaded (or you can upload your own) so you can order a bunch of custom-printed bottle caps for surprisingly cheap.
i haven't seen any post that shows how to make the bottlecaps, so, here is a link to someting i found
