Keychain - Blood Types

About This Model

These keychain blood type tags are practical 3D printed gear for quick identification when it counts. Each tag clearly marks blood type and attaches easily to keys, packs, or lanyards. The design comes as a pre-sliced file, ready-to-print with no tuning or setup, so you can produce the type you need without extra work. It fits into survival gear, medical kits, or everyday carry where clear ID matters. Use it in the field, on the trail, or around the homestead where response time can make a difference. It also works well in vehicles or group kits where multiple people need clear identification. The build holds up to regular handling and outdoor use. For field use and preparedness, it’s a simple outdoor tool that serves a real purpose.
