This keychain holder is designed to fit the MagicBand+ which is the newer model that works with the sculptures at the Disney theme parks.
Attach it to a keyring. For a really convenient option, attach the keyring to one of those drawstrings that attach to a pants belt loop.
I worked on this design with https://www.printables.com/@Bob_2986067 His great idea!
Print with TPU or other flex filament. I used Amazon Basics TPU. I would recommend using the provided .3mf file to generate your printer file where I have defined the supports for underneath the ears. The little bit of TPU supports are relatively easy and clean to remove with some snippers.
The MagicBand+ pops into place inside the holder with just a moderate amount of finger strength.
Enjoy!
