What makes the 357 Magnum box special


Caliber-specific fit
Each slot is designed to the caliber according to CIP dimensions: The cartridges are held firmly, play and rattling are minimized as much as possible. Dimensionally accurate design, not improvised.


Hinge lid with latch lock
The lid is attached at the back via a hinge and folds fully backward – the cartridges then stand upright and ready to grab in the securely fitting insert. A latch lock at the front keeps the lid securely closed during transport; to open, simply release the catch.


Stable & durable
Sturdily printed with thick walls: holds together in the gun cabinet, range bag, and at the range. Reusable instead of disposable box.


Caliber marking in multicolor print
The caliber marking is integrated directly into the box print in multicolor – permanent, without stickers or engraving. In a full gun cabinet, you immediately grab the right box.


For sport shooters, hunters, and reloaders


Reloaders: one box per load (powder type, charge, bullet) – batch cleanly separated and clearly marked in multicolor instead of mixed loads.

Sport shooter: one box per discipline or firearm – defined quantity per box, ammunition count at a glance.

Organized stock: uniformly labeled in the gun cabinet, ready for range, field, and range bag.


Made in Westerwald

We print every box here in Westerwald – no container import, no anonymous mass production. Printing is done mostly with solar power from our own 22 kWp photovoltaic system. Material: Filamelt PLA+ 2.0.


Frequently asked questions about the 357 Magnum box


Do my reloads fit too?
The box is designed for CIP-compliant cartridges. Custom loads with longer overall length (long bullets, shallow seating depth) can be tight near the upper OAL limit – if in doubt, ask briefly in advance.


Does the lid pop open in the backpack?
No. A latch lock at the front keeps the hinge lid securely closed so it does not accidentally open during transport. To open, release the catch with your finger; the lid then folds backward. Slight manufacturing tolerances are possible.


Are the boxes suitable for transport?
Yes, as an organizing and storage box for the range bag. However, it is not a safety container according to WaffG/AWaffV and not a hazardous materials packaging.


Can the box withstand heat (e.g., summer trunk)?
Designed for room and cabinet temperature and permanently dimensionally stable there. PLA remains temperature sensitive: prolonged heat, such as in a heated summer trunk, should be avoided.


What are the tolerances in 3D printing?
Due to manufacturing, slight tolerances are possible. The cartridges still sit firmly in the slot – a mi
Minimal play remains due to the design, and unnecessary pressure on the bullet nose is avoided as much as possible.
