3D Printed 105mm HE Replica Topper & Shell Casing

Complete your 105mm display with this full-size 3D printed replica inspired by the 105mm HE ammunition used aboard the AC-130. Choose the marked projectile-style topper for an existing expended casing, a full-size 3D printed replica shell casing, or both for a complete display.

Designed for military memorabilia collections, offices, squadron spaces, retirement gifts, and home displays.

Available Options

• Topper Only – Marked 3D printed 105mm HE-style topper designed to fit an expended 105mm shell casing
• Replica Shell Casing Only – Full-size 3D printed replica shell casing
• Topper + Replica Shell Casing – Includes both components for a complete display

Real expended shell casings are not included.

105mm Topper

The topper is 3D printed in multiple sections and permanently assembled before shipment. An internal dowel runs through the topper for added reinforcement and structural support. Printed markings are incorporated into the design to more closely represent the appearance of the original round.

The topper arrives fully assembled and ready for display.

Replica Shell Casing

The optional shell casing is fully 3D printed and designed to approximate the appearance and proportions of a real 105mm casing while remaining lightweight and suitable for display.

Fitment With Expended 105mm Casings

The Topper Only option is designed to fit expended 105mm shell casings.

Because fired casings can vary slightly due to manufacturing tolerances and heat expansion during firing, individual fit may vary. We have test-fitted these toppers with multiple expended casings and designed them for a secure fit.

Adhesive may be used if a permanent installation is desired.

Display & Finish

The topper and replica casing are printed in colors intended to closely represent the finished display and may be displayed as received.

Print colors may vary based on material availability. Slight variations in shade may occur between filament manufacturers.
