crystal geode 3d model

A mystical crystal geode cave backflow incense burner, solid 3D printable model. A cracked-open geode formation with rough rocky outer shell and a hollow interior lined with sharp angular crystal clusters of varying sizes pointing inward. Asymmetric organic shape, roughly 100mm wide and 80mm tall, sitting on a flat irregular rock base. At the very top center, a small flat circular platform (25mm diameter) with a 10mm hole drilled straight down through the center to hold a backflow incense cone. The internal channel runs vertically down through the geode and exits through several smaller openings at the base, between the crystals, allowing smoke to cascade outward and pool around the crystal points. Sharp faceted crystal geometry inside, rough natural stone texture outside. Witchy mystical aesthetic. Watertight single mesh, flat stable bottom, no overhangs above 45 degrees on outer surfaces, hollow internal smoke channel modeled as negative space.
