Stamp for leather, for wet cold stamping leather for belt, and wallet. Buckle holder and belt clip 38 mm.  I was making a Vault-Tec set for myself. With the help of 3D printing and photo editor and converter in SWG .  Just wet the skin, on the one hand the board (the plane is solid) on top of the wet leather (belt or billet for a purse) on top of the model, it is better to have a thin piece of plywood on top of it. And then we clamp the clamps while it is being tightened, but without fanaticism. We wait a couple of minutes, tighten, unscrew it will dry already with a pattern.  Repeat as much as necessary. Inspired by the universe of the divine game Fallout 2, because Vault 13. Just fans of the game .

P.S. You will feel when it becomes very difficult to twist, you can use a vise, but be careful, ideally a few clamps and pre-practice on a piece of leather. Like Fallout how i like that universe
