I love this! I wrote a book on the war on drugs (The War on Drugs: An Old Wives Tale) that was part memoir and part call to action - and in it I touched on the possible uses for hemp, but I hadn't even known about 3D printing using hemp plastics.
Phenomenal!
Even here in flyover country we are doing our best to fight for legalizing marijuana. It's an uphill battle, but it can be done.
