Easy Snap version Added no threads!

Bring unmatched realism to your training aids, ordnance collection, or technical displays with this premium 3D model of the AO-2.5PT Russian submunition, one of the most widely encountered Soviet-era fragmentation bomblets. This package includes both a full external model and a complete internal cutaway, featuring a fully detailed fuze assembly, striker, guide system, blocker components, internal ribs, and a true-to-life fragmentation pattern.

Comes with Stencil For painting text.
This File pack has 78 Files.

This model was built for high accuracy, using reference geometry from open-source documentation and technical imagery to create a museum-grade representation that stands above other AO-2.5PT models currently available.

Perfect for EOD training, ordnance demonstration, historical study, and display collections.

Included Files
Full Version

A complete external AO-2.5PT body featuring:

Accurate exterior ribbing

Correct ogive and casing thickness

Realistic fragmentation pattern geometry

Proper fuze well, striker channel, and top profile

Ideal for display or inert ordnance racks.

Cutaway Version

A highly detailed internal representation including:

Striker

Fuze guide system

Blocker & blocker spring

Striker channel

Internal ribs & cavity structure

True frag-pattern inner casing

All internal shapes modeled as individual bodies

Designed for educational use, demonstration, or X-ray simulation.

X-Ray Capable Design

To replicate radiographic appearance, simply apply aluminum tape to the internal components before assembly.
This gives:

Clear density contrast under X-ray

Visible striker & blocker orientation

Accurate fuze/firing train depiction

Realistic fragmentation outline under imaging

Perfect for EOD schools, training lanes, or tech-intels.

Required Hardware (for functional internal movement)

To complete the fully detailed fuze system, you will need the following small rods & springs:

Rods

1.5–1.7 mm dia rod, 18 mm long ×2 (Guide Rods)

1.5–1.7 mm dia rod, 13.5 mm long (Striker Rod)

Springs

Guide Spring: 2–2.4 mm dia, 0.2 wire, 10 mm long

Blocker Spring: 4.5 mm dia, 0.2 wire, 6 mm long

These allow the internal fuze components to move smoothly and match real mechanical behavior.

Premium accuracy for training, collectors, and display

Historical Background

The AO-2.5PT is a Soviet submunition used in cluster bombs and dispensers, known for its distinctive internal striker fuze and fragmentation body. Its simplicity and reliability led to widespread use, and it remains common in many regions today. This model recreates its mechanical components with high fidelity to support training, analysis, and safe ordnance familiarization.

⚠️ DISCLAIMER

This is an inert, non-functional training aid.
It contains no energetic materials and cannot be made functional.

3D Printing Instructions

The Real version used thread locker it can be diffucult to screw togeather use glue and let dry per thread. you will notice the threads will unscrew when trying to put togeather each piece the glue fixes that issue

This model contains very small internal parts, especially inside the fuze assembly.
For best results:

Resin printing is strongly recommended for the highest detail and proper fit.

For FDM, use a PETG interface with PLA to help the small components fit correctly and reduce breakage.
