Waiiiit whaaaat how!

Hey guys I’ve been messing around with 3d printing for about a few weeks now. I am a complete beginner with no experience or training, or even a dam teacher.
The main reason I want to learn how to model is so I can justify buying a 3d printer :evilgrin:
My buddy who is in design school turned me onto Rhino so I started to learn their program and tools from various tutorials and he taught me a few tricks. But now I’m realizing once the trial is over, I can’t afford that shit!
I found blender and its totally different from rhino. Ive gone through tutorials like the cup tutorial and ya that was easy but it was because I was following steps!

NOW my question is!! Are there any online courses or something that would help me learn to 3d model in general, but with blender specifically???
