M42 B40 Submunition - Full & Cutaway Model Pack (Non-Functional, Scale Replica)

This download contains a professional, scale-accurate, non-functional 3D model pack of the M42 Submunition delivered as two main variants.
Over 27 STLs!

• Full-Up Replica — complete external geometry for display and scale modeling with internal components included for realistic appearance (all internal parts are visual, inert, and non-functional).
• Cutaway Replica — half/sectioned exterior revealing internal geometry for classroom and visual training use (internal components are visual representations only).

What you get

Optimized STL files for hobby/desktop 3D printing (separate parts where useful).

Full and cutaway bodies split into printable sections for small bed printers.

IMPORTANT — Small parts & printing advice

This pack includes very small parts of the fuze details Files are provided at 1:1 real-world scale. If you want reliable printing of the fuze components, consider either printing those parts in resin for higher fidelity or scaling the model up slightly to make the small features printable on FDM machines. Resin printing is recommended for the best detail on the tiny fuze pieces.
