Modular 3D Printable Victorian Dollhouse

I’m putting together a Christmas-themed light-show display and need a Victorian-style dollhouse that I can 3D-print at home on a 250 mm × 250 mm build plate. The delivered files should be individual STL files of parts so that I can print and assemble them together. You should not create one single STL for this house. Snap-fit tabs, keyed edges, or dowel slots that keep the structure rigid after assembly are strongly preferred; glue-only joints should be kept to a minimum. You must create an original design that does not violate intellectual property rights or copyright of any kind. Please see the attached reference photos for inspiration. My specific asks are that you include a minimum of two floors, at least 5 windows, and have the roof facing the viewer like in the reference photos. Deliverables • Clean, manifold STL (or 3MF) files for every individual part, each sized to fit within a 250 × 250 mm print bed • An exploded view or PDF assembly guide that labels the parts and shows recommended print orientation • Brief notes on print settings you found effective during test-slicing (layer height, supports, infill) • Transfer of full ownership and commercial rights to the model - Original design file (such as the .F3D) in the event I need to make edits to the design myself.
