Description
For precision shooters, maintaining the integrity of each handloaded round is paramount. This 3D-printable 20-round ammunition box is specifically designed for the .308 Winchester family and similar short-action cartridges. Its compact format is ideal for a single string of fire or a quick hunting session, providing a professional and organized alternative to bulky commercial packaging.
Precision-Fit Cells: Each cartridge is held securely in an individual slot to prevent movement and protect the bullet tips from impacts that could affect ballistic performance.
Compact & Portable: The 20-round capacity is designed to fit easily into a jacket pocket or a small compartment in your range bag.
Heavy-Duty Protection: Built to withstand the rigors of the field, offering much better protection against moisture and crushing than standard cardboard boxes.
Stackable Architecture: Features an interlocking design for stable stacking, perfect for organizing different load developments in your storage safe.
Material: PLA, PETG, or ABS. PETG is highly recommended for its superior impact resistance and flexibility, especially for the latch or hinge areas.
Layer Height: 0.2mm for a high-quality finish and reliable structural strength.
Walls/Perimeters: At least 3 wall loops to ensure the corners and the lid closure remain robust.
Infill: 15% to 20% (Gyroid or Grid).
Calibration: Ensure your printer's dimensional accuracy is dialed in so the cartridges sit snugly without being forced.
Insert your .308 Win (or similar calibers like 6.5 Creedmoor or 7mm-08) rounds into the grid.
Snap the lid shut for a secure seal during transport.
Use the flat surface of the lid to apply a label or write your specific load data (bullet weight, powder charge, OAL) for quick identification at the range.
