This is a remix of the Rugged Parametric Box by Whity, which was remixed by groog adapted for 9mm ammunition storage. This version integrates a removable ammo tray and includes all source files for further customization.

This model supports 20x and 25x tray capacities.

If you are looking for larger capacity versions, see 50x, 100x, 150x, 225x, 396x sizes here.

These models use 3 [M3x30mm] Screws. Fusion3d files are provided for changing screw length & thickness.

While the box remains fully parametric, the ammo tray, however, cannot be completely parametric due to geometry operations that must be done manually after changing grid size.

If creating a custom tray size in Fusion, complete the following steps:

1. Set desired column and row quantity (Core 1 max: 18 deep x 22 wide)
2. Apply fillets to the inside and outside outer corners of the tray
   • Outer corner: 5 mm
   • Inner corner: 4 mm
3. Apply a chamfer to the bottom edge of the tray
   • 1.5 mm to 1.7 mm recommended
4. Measure the distance between the outer walls
5. Update the box file using those measured dimensions

Because these features reference changing interior geometry, they will not regenerate automatically through parameters alone.

All Fusion 3D files are included so you can modify and rebuild as needed.

• 3mf files
• Fusion 3D source files
• GCode for CoreOne

The 3MF files preserve color configuration for multi material systems.

Tested in PLA and PETG

Layer height: 0.2 mm
Supports: Not required
Walls: 2-3 perimeters recommended
Infill: 15 to 25 percent

Print tray and lids flat on the build plate. If modifying dimensions, verify fit before printing the full box assembly.

Long Term Storage Note

This model includes a gasket seal to improve air resistance. For long term storage, consider adding a desiccant pack or using a dedicated ammo can. The designer assumes no liability for ammunition condition during storage.
