This is the first 3D printable Black Hole in all time. (thanks to prusa3d)

WARNING: Black holes are extremely destructive, make at your own risk.

We have done math and the specs we have provided are correct.

IMPORTANT: To print properly you MUST scale the model by 148,980,000,000,000%.

Printing Tips for Printing Black Holes:

• Supports: yes
• Infill density: 100%
• Scale: 148,980,000,000,000%

While most will indeed need black holes it has been brought to our attention that some (without saying names) do not. So we have an alternative:

All you need to do is scale it based on the chart below and you can have all the spheres you could ever imagine!

Scale by given percentages.

1. Golf Ball: 42.67%
2. Tennis Ball: 67%
3. Beach Ball: 545%
4. Grapefruit: 100%
5. The Stay Puft Marshmallow Man's Head: 3,621.98%
6. Brain Cell: .01%
7. Ping Pong Ball: 40%
8. Chicken: 180%

Seriously though, If you were to actually print the model at the 148,980,000,000,000% scale it would collapse into a black hole of approximately 1,000,000 solar masses (We've done the math.)
