T7 phage Keychain

This T7 phage version was created inspired by the Bacteriophage virus keychain (https://www.thingiverse.com/thing:2745980).
Bacteriophage T7 (or the T7 phage) is a bacteriophage, a virus that infects bacteria. The virus has complex structural symmetry, with a capsid of the phage that is icosahedral (twenty faces) with an inner diameter of 55 nm (https://en.wikipedia.org/wiki/T7_phage).

The model can be printed without the need for supports.
