Narrow Modular Dishwasher Gap Shelving Unit

Design a fully enclosed, ultra-narrow, vertical 3D-printable shelving unit designed to fit into a precisely measured space next to a dishwasher inside an IKEA kitchen cabinet. EXACT MAXIMUM EXTERNAL DIMENSIONS: - Height: 870 mm - Width: 113 mm - Depth: 150 mm These dimensions are strict maximum limits. The assembled unit must fit within this space without exceeding any dimension. CONSTRUCTION: - Two continuous-looking, solid, opaque side panels (left and right). - One thin, solid, opaque rear panel. - Open front for easy access. - One solid bottom shelf. - One solid top shelf forming the upper frame. - Three additional intermediate horizontal shelves. - Five horizontal shelf levels in total, including the top and bottom. SHELF SPACING: - The clear vertical distance between the bottom shelf and the first intermediate shelf must be at least 300 mm. - The clear vertical distance between the first and second intermediate shelves must be at least 300 mm. - The remaining upper section should accommodate the third intermediate shelf, with approximately 200 mm spacing to the top shelf. - Distribute the shelves to maximize usable storage space while respecting these minimum clearances. MATERIAL EFFICIENCY: - Minimize filament consumption while maintaining sufficient structural rigidity. - Use thin but mechanically reinforced side walls and rear panel. - Use ribs, localized reinforcement and optimized geometry instead of unnecessarily thick solid walls. - Avoid unnecessary material in non-load-bearing areas. - All shelves must be structurally supported by both side panels. MODULAR 3D PRINTING: - The entire structure must be divided into smaller components suitable for a standard FDM 3D printer. - Design reliable mechanical connections between individual components using alignment pins, sockets, interlocking joints or snap-fit connections. - Prefer simple pin-based connections that can be glued if necessary. - Ensure accurate alignment and rigidity after assembly. - Avoid unnecessarily complex connectors. - Divide large side panels and rear panels into printable segments. IMPORTANT DESIGN CONSTRAINTS: - The assembled structure must be rigid and self-supporting. - No exposed scaffolding, open frames, rails or transparent/open side structures. - Both side walls and the rear panel must remain opaque. - The front must remain completely open. - All components must be designed for practical FDM printing. - Account for realistic printing tolerances and assembly clearances. OUTPUT: 1. Complete 3D CAD model. 2. Separate STL files for every printable component. 3. Assembly visualization. 4. Assembly instructions. 5. Exact final assembled dimensions. 6. Estimated filament consumption and print time. Prioritize dimensional accuracy, mechanical functionality, material efficiency and ease of assembly over visual aesthetics.
