Leather Ammo Holder Wet-Mold Form

Bring precision and consistency to your leather crafting with this 3D-printed wet-mold form — designed specifically for creating professional-grade leather ammo holders.  4 sizes - 6, 8, 10, and 12 round options available.  Added a version for 12ga shells.  Other versions in the works, let me know what you want first. 

Each cavity is engineered with smooth, rounded contours that help the leather stretch evenly and form clean, crisp edges during molding. Whether you’re crafting for display, EDC, or functional holsters, this form ensures repeatable, uniform results every time.

Features:

• 🧰 Optimized for wet-molding: allows even pressure across all holders.
• 🎯 Designed for standard .357 cartridge sizes (adjust model scaling or cavity dimensions as needed for your specific caliber).
• 💧 Smooth radii prevent creasing and tearing during forming.
• ⚙️ Can be clamped, vacuum-formed, or hand-pressed — compatible with traditional wet-molding techniques.

Recommended Settings:

• Print in PETG or PLA+ for stability and durability.
• 0.2 mm layer height or finer for smoother finish.
• 15–30% infill is sufficient for general use.

Usage Tips:

1. Soak veg-tanned leather until pliable and no more bubbles appear.
2. Lay it over the mold and press into shape (by hand, vacuum, or with the press). 
3. Allow to dry fully before trimming or stitching – 24 hours after removing from mold.
