Description

Introducing a custom-designed 300 Blackout ammunition storage solution: a compact box engineered to securely hold 20 rounds of 300 Blackout  ammunition. The design features a innovative sliding container mechanism that nests neatly into a reinforced stackable lid, secured by dual integrated latches. These latches are easily depressed for quick release, allowing smooth separation of the container from the lid while ensuring reliable retention during transport or storage. Printed in-place as two functional components—no assembly hardware, supports, or post-processing required. The model is fully optimized for reliable results using PLA or PETG filaments, delivering excellent structural integrity, and a clean, professional finish straight from the printer. 

 

Key features include:

  • Capacity: 20 rounds (300 Blackout)
  • Mechanism: Sliding container with dual positive-latching system
  • Print-in-place design: Two-piece assembly with built-in functionality
  • Support-free printing: Minimizes material waste and simplifies production
  • Material compatibility: Performs optimally in PLA or PETG for durability and ease of use
  • Single and two Color Options
  • Optional glue in customizable faceplate

Ideal for range organization, safe storage, or as a modular addition to any reloading or shooting setup. Stackable and robust, this practical design combines functionality with straightforward printability.

 

I plan on adding  many more calibers. If I don't have the one you need let me know in the comments and I will get it added.  Other calibers can be found by clicking on the picture below.
