observation tower 3d model

Detailed dice tower model inspired by the architecture of the Näsinneula observation tower in Tampere, Finland. The tower's entire central shaft must be HOLLOW inside and contain internal ramps for dice rolling. The model must be visually segmented into three distinct stackable parts for 3D printing: 1) The broad base section, which includes a low, fenced dice-exit courtyard. 2) The **TALLEST** central shaft/mid-section (long internal dice path). 3) The conical top section (dice entry point). Material: rough concrete texture with minimal glass and metal accents. The overall height should suggest large scale and be suitable for separating into three distinct pieces.
