WW2 Japanese Anti-Tank Lunge Mine

UPDATE: 20-4-24 (improved STL quality for smoother prints and added split warhead option for smaller printers)

Full size imitation of the kamikaze anti-tank 'lunge mine' used in last-ditch banzai charges by Imperial Japanese Army soldiers towards the end of WW2. Some were also used by Vietnamese forces in the First Indochina War.

Prints in 5 parts - striker body, warhead and three 'feet' which set off the mine when it was struck with sufficient force against a tank. The warhead and striker body are securely locked together by a hex protrusion and should be glued for max strength.

I updated this with an option to split the warhead in half, as it's quite large and most printers would not be capable of printing it in one piece. The split files have an integral hex extrusion in the lower piece which slots into a hex-hole in the upper piece which aligns and secures the two parts.

I do not include the handle as it's obviously way too big to be printed, you should make one from a ~1700mm (67") length of wooden rod 38mm (1.5") in diameter. Some fitting will be required and then you'll have to finish by drilling the safety pin hole through the handle after it's been inserted using the pre-made holes in the striker body as a guide.

I have also included the safety pin as an STL but only so you can see the shape in order to make your own from 3mm wire.

These are super rare to get because most of them were destroyed or simply rusted away where they were left in the jungle. Making a repro is almost the only way to have one now.

Would make an interesting addition to any WW2 Japanese militaria collection or as an accessory for a re-enactment kit!

(Note: This is a cosmetic imitation only, it cannot function or be made to function as a real device. I am not responsible for any mis-use of the printed items. The renders showing paint colours and markings are for
illustration purposes only - I don't provide stencils or paint guides unless specifically mentioned in the description.)

A big printer is required! You need at least 200mm in both X and Y axes and 170mm in Z-axis (height) to print the warhead. If you have a very large CoreXY-style printer with at least 275mm Z-axis, you can print the warhead as a complete part.

There is not a ton of detail here so I recommend using 0.20mm or bigger layers on the warhead and 0.16mm for the striker body and feet.
