Two towers, four levels. Each tower stacks a base keep section beneath a middle keep section, forming two open shelf levels sized to hold one DGX Spark unit (5.9 x 5.9 x 2.0 in) apiece. The twin towers, four levels total, are linked at height by a sky bridge, unifying the pair into one display stand.

Fifteen pieces that fit together. The shelf comes as 15 separate printed pieces: left and right base keep sections, left and right middle keep sections, left and right parapet caps, one sky bridge, and eight turret roofs that cap each corner tower, all fitting together to form the finished twin-tower castle.

Turrets, arches, and battlements. Crenellated parapets line the rooftop of each tower, while arched window cutouts break up the keep walls below. Eight tapered, conical turret roofs cap the corner posts, and the fine layer finish keeps every edge and curve crisp, giving the whole piece a clean, toy-castle silhouette.
