OE 155 56/69 Proyectil de artillería francés de 155 mm y M557 PD T-BAR FUZE Bundle

Full Model + Cutaway + Extended Booster + US Fuze Adapter + M556 T-Bar PD Fuze (High-Detail Internals)

This bundle includes both fired and unfired rotating bands, allowing you to swap between live-configuration appearance and a post-firing, engraved rotating band for realistic training and display options.

A total of 84 individual components are included in the full model set, giving you unmatched fidelity and modularity for printing, assembly, and instructional use.

This premium 3D model pack recreates the French OE 155 56/69 artillery projectile, including its extended booster section and a purpose-built adapter allowing it to accept U.S.-pattern point-detonating fuzes.
Also included is a fully modeled M556 T-Bar PD Fuze, complete with extremely detailed internal components and a clean instructional cutaway version—ideal for EOD, UXO, intelligence, training, and museum display work.

All components are 100% inert replicas with no energetic materials.

Historical & Technical Background

The OE 155 56/69 is a French-designed high-explosive artillery projectile that traces much of its form and proportions to earlier U.S. ordnance. After WWII, French engineers reverse-engineered and adapted several American 155mm shell bodies for domestic production. The OE 155 56/69 emerged as a modernized derivative—retaining the proven ballistic profile while incorporating French manufacturing standards, updated metal treatments, and compatibility changes for locally produced boosters and fuzes.

As NATO interoperability grew, many units later field-modified these projectiles using adapter collars for U.S.-pattern point-detonating fuzes such as the M556. This blend of French shell design with American fuzing allowed widespread export, standardized logistics, and simplified training for multinational artillery units.

This model bundle recreates the full configuration—shell + extended booster + US fuze adapter + M556 fuze—as commonly documented in service and training environments.

3D Printing Recommendations

PLA for general printing; PETG as an interface layer if using multi-material supports for cleaner separation

4–8 walls for structural durability

15–20% gyroid infill for shell bodies

Optional multi-color printing to highlight boosters, adapters, and fuze internals

Two small springs are required for optional functional demonstration of fuze mechanisms (not included):

Spring 1: 9 mm diameter, 10 mm length, 0.5 mm wire

Spring 2: 4 mm diameter, 11 mm length, 0.25–0.5 mm wire

These are standard hardware-store compression springs and are not specific military components.
