Dart holders with a name round the case and "I heart" keychains, gifts you can print tonight.
Everything here is a finished object, not a mold: you print it and give it away. The dart holders look like a small dartboard, with a hole in every wedge for a dart to stand point down and a name or a phrase raised round the case, like DAD'S DARTS or LOCAL PUB. The keychains are the souvenir "I heart" style in black, white and red, with any word you like.
Neither needs a multi-material printer. The keychains change colour twice with a filament swap at heights listed in each zip, and the dart holder comes as separate parts (case, face, ring) that you print one colour at a time, plus a 3MF if you do have an AMS or MMU.
Every design was made with a free generator, so if the name you need is not here, type it in and download your own in about a minute.
Questions
Add a filament change (pause at height) in your slicer at the heights the keychain's PRINT-SETTINGS sheet lists, swap the filament when the printer stops, and let it carry on.
PETG for a keychain, since it bends rather than snaps and does not soften in a hot car. PLA is fine for a dart holder that sits on a shelf.
Yes. Open the generator from this page, type the name or word, check the preview and download the STL. The letters are sized to fit the space automatically.
