The Oxygen Destroyer (オキシジェン・デストロイヤー Okishijen Desutoroiyā) is a fictional chemical weapon of mass destruction invented by Dr. Daisuke Serizawa and used to kill the original Godzilla in the 1954 film Godzilla. It has appeared or been referenced in several other pieces of official Godzilla media since then.

Using a 3D printer and plans published online, I built a 1:1 scale model of the famous Oxygen Destroyer from the original Godzilla movie.

Crucial elements if you want to make one:
- Small meter
- 3D Printer
- Metal rods (8mm x 300mm 304 Stainless Steel Solid Round Rod)
- Acrylic tube (Acrylic Pipe Clear Rigid Round Tube 145mm ID 150mm OD 10″)
- 3D printer plans and instructions https://www.thingiverse.com/thing:4726028


Some smaller, available models:

How does it work?
The Oxygen Destroyer is a heavy device composed of a metal capsule with a glass central chamber. Within this chamber is a second capsule attached by rods at either end. Contained within the capsule is a large amount of what would be later known as Micro-Oxygen, the weapon’s payload.
Numerous gauges and pressure meters are present on the larger capsule. To operate the Oxygen Destroyer, the two ends of the larger capsule have to be pushed inwards. This causes the rods to secure the inner capsule to pull apart, releasing the Micro-oxygen within.
Who invented the Oxygen Destroyer?
The Oxygen Destroyer was the invention of Dr. Daisuke Serizawa. Having devoted his studies to the element oxygen, Serizawa accidentally stumbled upon a volatile and deadly chemical reaction. Though horrified by the destructive potential of his discovery, he nonetheless continued his research, optimistic that some beneficial outcome could be produced from it.

What are the major drawbacks from deploying the Oxygen Destroyer?
Creating more monsters. Destoroyah, is a monster created by the Oxygen Destroyer use in 1954.

Do we have to fear an Oxygen Destroyer arms race?
Dr. Serizawa recognized that his discovery could be used as a weapon and thus destroyed all of his research and himself in the final attack on Godzilla. On the fateful morning in Tokyo Bay, Serizawa and Hideto Ogata descended into the water to find Godzilla, with Serizawa carrying the Oxygen Destroyer.
Ogata was sent back to the ship while Dr. Serizawa stayed behind and detonated the weapon.
