obsidian spire 3d model

3D printable STL supportless miniature terrain, a towering razor-sharp obsidian needle spire for Age of Sigmar Aqshy style. Monolithic volcanic glass shard designed for FDM supportless printing, featuring a wide stable footprint that tapers continuously upwards at smooth 45-degree angles to a sharp peak. Faceted jagged rock textures with clean self-supporting overhangs, deep vertical fissures, and zero floating details. Flat solid bottom base, clean geometry optimized for supportless FDM layer extrusion at 28mm scale, unpainted clay render style --no horizontal overhangs, no floating debris, no undercut angles, no delicate branches, no supports required
