Crystals terrain
thingiverse
I've followed [this](https://www.youtube.com/watch?v=U-334eAXnSM) tutorial on creating crystals in Blender. Simple and detailed, I'd definitely recommend it. Model is plain simple, it's working just fine without any supports. I like how it looks with low detail 0.28 layer, gives this stalactite-ish layered look.
