Đạo cụ Brass Knuckles/Knuckle Duster in 3D (Public Domain)

This is a 3D printable brass knuckles prop designed strictly for display, cosplay, film, photography, and educational demonstration use. The model is intentionally styled as a non-functional prop and should be printed with rounded edges and lightweight materials to remain safe and convention-friendly.

The design is released into the public domain, meaning you are free to print, modify, remix, share, and use it commercially with no restrictions. It’s ideal for costumes, stage props, themed displays, or historical replicas where real or functional items are unsafe or prohibited.

Optimized for easy printing, this model works well on FDM and resin printers, can be printed as a single piece, and requires little to no supports depending on orientation.

⚠ Prop only. Not intended for real-world use, impact, or harm.
