Tower Crane Mast

The connecting part the crane climbs on: a 2 m square lattice mast of 3 m sections with corner angles, k-bracing, a bolted flange plate top and bottom and an internal ladder with rest platforms, galvanised grey; height knob 1..12 sections.

风格：low-poly, flat-shaded vertex colors, no textures, single shared material, so any set of these merges to one draw call; shares palette and scale with its kit
