Architectural PDF drawings to 3D printable file for a multistory building

About the project

Turn our architectural PDF set for a multi-unit residential block into 3D print files for a physical scale model. The model must come apart. Each floor lifts off the one below so you can look down into the unit layouts; the roof lifts off the top floor. A stack of open trays. Not a rendering. Production-ready print files. Printer Bambu Lab X2D, dual nozzle, 0.4 mm. Design every part to fit 230 × 245 mm — the headline 256 mm isn't usable, and the envelope shrinks to 235.5 mm when the second nozzle runs. Rules You pick the scale, and show your working. Every interior partition must come out 1.0 mm or thicker on the model — thicken where true scale falls short, and tell us by how much. Max 12 printed parts. Split at floor level first; split vertically only along a wall line, never through a room. Floor-to-floor joint: continuous downstand lip, 3–5 mm deep, 0.25–0.30 mm clearance per side, 0.5 mm chamfered lead-in, plus 3 asymmetric dowel pins. Same joint at every level. No frames, mullions or door leaves — too small to print at this scale. Openings only. Design it to print support-free. Deliverables Watertight manifold 3MF per part — must pass Blender's 3D Print Toolbox with zero errors and a 0.8 mm thickness check. Send the screenshots. Editable source model — STEP preferred. Bambu Studio project with parts laid out on plates. One-page assembly note: part list, print order, chosen scale, and every place you departed from true scale.
