I posted a video on how to design a planter in under 5 minutes with free web based software, but the same methods can be used to make all sort of 3d models, I really encourager y'all to try and especially get your kids involved as 3d printing is one of the technologies that is now at the forefront of a technological revolution that will be even more impactful than the first industrial one, Along with 3d printing, blockchain and A.I will change the world in ways we can't even imagine and its just the beginning.
If you do end up trying to make some 3d models be sure to tag me as I would love to see your creations and It will make me feel real nice I am influencing people in a positive manner.
