A non-functional replica of the Soviet PMK-40 anti-personnel mine for reenactment and demonstration. These small pressure-sensitive mines were introduced in 1940 and were produced from Bakelite, then later from compressed cardboard due to wartime shortages. They would often be deployed together with larger anti-tank mines in mine fields by the Red Army. 

The reported size of the device seems to vary, but I went with a diameter of 70 mm as that was the most commonly cited measurement. If anyone has any concrete opposing data, I'd be happy to modify it.

Included an empty version for a faster print as an empty container. Also a solid simplified version for other uses.

Printing

Print the body upside down to have the exterior look as good as possible. I've included some break-away supports so no additional supports is required, though can be used to shorten bridges. Let me know if there are any issues. Lid could benefit from a brim if you have adhesion problems. Designed for a 0.4mm nozzle.

Update 2023-06-22: Added alternate lid and stopper
