3D-Printed Tactical Self-Defense Keychain

This keychain was modeled and 3D-printed with an ergonomic and tactical design. Crafted from a robust filament (specify the filament if you wish, e.g., PLA, PETG, ABS), it features an elongated and grooved shape for a secure, non-slip grip. The pointed (or rounded/conical) ends are designed to serve as a portable, lightweight, and discreet self-defense tool. It easily attaches to your keyring to ensure it is always within reach.

The supports for the print are included in the model.
