Crystals terrain
thingiverse
I've followed a simple tutorial on creating crystals in Blender. The video provides detailed instructions that are easy to follow. I'd definitely recommend checking it out. The model is straightforward and works perfectly without any supports. I like how it looks with low detail settings, giving it a stalactite-ish layered appearance when set at 0.28 layer level.
