Bill of Materials
Description
Hello,
Practical .357 Magnum ammo storage box designed for secure, organized, and efficient ammunition storage.
This box holds up to 100 rounds and is optimized for range use, transport, and long-term storage.
Features:
• Holds 100 rounds of .357 Magnum
• Clean and efficient internal layout
• Durable print-friendly design
• Secure storage for transport and range use
Internal design includes ~5–6 mm additional length per round to allow foam compression (recommended 10–15 mm foam layer in lid).
This model is part of a modular ammunition storage system designed for multiple calibers and shell sizes.
Box was printed in PLA, latches in PETG HF, and seal in TPU.
Seal is not necessary for the function of the print.
I used a carbon fiber effect plate and it looks great.
All parts are connected with M3x30 bolts.
You will need 6 pcs.
