Modular Architectural Model for FDM Printing

Project title: Redesign a large modular architectural model for FDM 3D printing

I need an experienced CAD designer to redesign my existing architectural building model for a client expo.

The final building should be large and visually impressive:

- Main building: approximately 40 cm wide × 30 cm deep × 37 cm high
- Complete display with entrance and boundary: approximately 44 cm × 40 cm × 37 cm
- Printer available: Bambu Lab A1, 256 × 256 × 256 mm build volume
- The model must therefore be redesigned as smaller modular pieces, each fitting comfortably within a 23 × 23 cm print area.

I already have existing 3MF files and reference images. Keep the general building style, entrance, gate, façade details, and architectural appearance, but redesign the model properly for large-scale modular FDM printing.

Requirements:

- Design modular floors, walls, roof, façade panels, entrance, gate, and boundary components.
- Use strong alignment pins, sockets, tabs, or interlocking joints with proper FDM clearances.
- Design printed front entrance/boundary parts.
- The left, right, and rear boundary sides will use 3 mm plywood panels, so create printed corner posts and 3.5 mm slots/rebates to hold those panels.
- Use 0.4 mm nozzle-friendly design for large structural parts and retain fine detail parts suitable for a 0.2 mm nozzle.
- Minimize supports and make all parts practical to print on a Bambu Lab A1.
- Create a clear numbered assembly system.

Required deliverables:

1. Editable native CAD source file: Fusion 360, SolidWorks, Onshape, or equivalent
2. STEP files
3. Separate print-ready STL and/or 3MF files for every module
4. Bambu Studio-ready plate arrangement or recommended print orientation
5. Assembly guide with numbered parts, joining method, and print settings
6. One small test module with connector parts before the full final delivery

Please apply only if you have previous experience with FDM 3D printing, modular assemblies, tolerances, and architectural scale models. Please share examples of similar printable CAD work, not only 3D renders.

I will share the existing 3MF files and reference images with shortlisted freelancers.
