Make a splash with this little puddle keychain. This charm has a secret compartment with a snap on lid. Inside you can place magnets, NFC tags or other small bits.

Printing Guidelines

0.16mm layer height, print solid.

The inner compartment is 3.6mm tall and 19mm in diameter. I just put three 3x6mm magnets in loosely for hanging on a magnet strip. The snap on lid should be a nice tight fit that doesn't require glue, but if you were to scale up the model and throw an airtag inside--for example--you might want to glue everything together with E6000 or another adhesive.

Keychain holes are designed for a jump ring of roughly 9-10mm diameter, as common with keyrings in bulk (on Amazon).

Photographed models were printed on the Bambu Lab X1-Carbon 3D Printer using Bambu Lab PLA Matte Grass Green.
