It's really some form of CC-BY-SA-NC plus some more limits about "safety" which is impossible to define and prove or disprove and none of the creators business.
Basically it's almost untouchable until the terms are actually defined and made sensible.
Even the simple "only for hobby/personal/educational use" is internally inconsistent because education is itself a commercial activity.
Trying to say too much in the license is just wasting an exceptionally cool project. Just make it CC-BY-SA, add the warnings and disclaimers, and leave it at that. Only add the -NC if you want to sell them and be the only one allowed to sell them. If you aren't planning to sell them as an important part of your own livlihood, then don't add -NC, it doesn't make the world a better place.
