Unleash a little harmless chaos with the Dragon Fang (龙牙) — a fully 3D printed dagger that looks like it belongs in legend, but is built for fun. 🐉⚔️

This dragon-themed prank dagger features a clever retractable blade with a spring-back action. On contact, the blade smoothly slides in… then instantly springs back into place, creating a realistic (but completely safe) effect that’s perfect for pranks, cosplay, or dramatic reveals.

The blade is embossed with “Dragon Fang Awakens” (龙牙觉醒), giving it that ancient, mythical aura, while a raised red dragon design winds along the blade, adding bold detail and presence. It’s the kind of piece that looks like it should hum with power in a fantasy world.

Every component is 100% 3D printed, designed to work together for a satisfying mechanical action without the need for metal parts. Just print, assemble, and let the dragon do the rest.

What makes Dragon Fang (龙牙) especially great is that it’s safe for all ages, and here’s why:

The blade is not sharp 
The retractable mechanism absorbs impact, preventing force from being transferred
The spring-back action is light and controlled, designed for play, not power
No metal parts are used — it’s 100% 3D printed
Every part is printed and assembled to create a smooth, satisfying action while keeping safety front and center.

Perfect for:

Pranks and safe scares
Cosplay and props
Display pieces with personality
Showing off creative 3D printing mechanics
Dragon Fang (龙牙) — strike, retract… and rise again. 🐲✨
