minsk planetarium tower 3d model

Highly detailed 3D model of the Minsk Planetarium Observatory tower, small lighthouse-style cylindrical building in Soviet modernist style, 1967. Perfect white concrete cylinder, diameter 5.5 m, height 10 m. Full panoramic vertical glass windows all around the cylinder, divided by thin white pillars. At the top — circular balcony with black metal railing. External black metal spiral staircase wrapping around the entire tower from ground to balcony. Classic segmented observatory dome on top (gray metallic panels, smooth rounded shape, height 2 m). Slightly elevated concrete base with small entrance door at the bottom. Flat bottom for easy 3D printing, wall thickness minimum 3-4 mm everywhere, manifold watertight mesh, no thin parts, optimized for FDM printing. Highly realistic proportions and symmetry, clean geometry, no people, no trees, no extra objects. Scale: printable at 15-25 cm height.
