Description
This is a 3D printable replica of the famous “Demon Core” — a plutonium sphere used in the Manhattan Project and involved in two criticality accidents at Los Alamos during the 1940s. This model is purely a historical and educational display piece, designed for makers, history enthusiasts, and science fans.
The print captures the simple yet striking form of the core, making it perfect as a desk ornament, conversation piece, or teaching aid when discussing nuclear history, physics, or the atomic era.
- Fully safe – no radioactive materials, just plastic!
- Easy to print with standard slicer settings
- Works well in metallic or glowing filaments for dramatic effect
- Scales up or down depending on your printer size
Bring a piece of atomic history into your maker space — a reminder of science’s power, risks, and legacy.
