This floating keychain is designed to keep your keys from sinking if they fall into water — perfect for boating, fishing, or any waterside activity.

It’s compact, lightweight, and prints in one piece. The design has enough volume and internal air to float a small key bundle (1–3 keys depending on material and infill). You can easily attach it to your keyring with a simple loop or clip.

Want to make it more personal? Add your name or phone number on the side before printing.

Note: Always test flotation with your actual keys to ensure it’s buoyant enough. Add multiple floaters or enlarge the print for heavier sets.
