Belt buckle for 30mm width belt

Base on my original work, I add some decoration on the surface of the buckle.

Most belts have metal content which may trigger an alarm when you walk through the airport check gate. passengers are always asked to unbuckle the belt themselves. This 3d printed belt buckle content no metal! try it, and give me some feedback!

you should prepare:

6mm leather punching tool. reference the picture I attached.
