Blood Type Drop Keychain

This 3D-printed model set features keychains shaped like stylized blood drops, each marked with one of the eight major blood types: O-, O+, A-, A+, B-, B+, AB-, and AB+. Designed to combine medical awareness with personalization, these keychains are perfect for everyday carry on bags, backpacks, keyrings, or emergency kits.

Each tag is compact, lightweight, and has a small hole for attaching to keychains or lanyards. The high-contrast two-color print (recommended in red and white) makes the letters clearly readable. This can be a life-saving identifier in emergency situations or simply a unique and thoughtful accessory for medical professionals, blood donors, or healthcare students.

The set includes all possible blood type variants, so you can print the exact one that suits you or your loved ones. Also ideal as a thoughtful gift, hospital staff badge addition, or community blood donation promotional item. No AMS required – print one at a time using filament swaps or multicolor settings.
