Loom Band Tool
thingiverse
I created these to my kids' exact specifications, so they should match what they're looking for perfectly. You'll need to scale them up to fit your printer - aiming for a size that's as large as your printer can accommodate is usually safe. There are two different versions available: one with a blunt tip and another with a pointy tip. To print these correctly, position the tool end facing downwards and make sure the handle points upwards towards you. As an added bonus, neither version needs any extra support to print securely.
