Modular Can Rack – Exploded Components

Text-to-CAD Prompt (Condensed) Design a simple, manufacturable MVP CAD assembly for a modular sliding can rack system for a portable snack refrigerator. The goal is to demonstrate the concept, not create a production-ready product. Prioritize minimal part count, easy 3D printing, simple assembly, and functional proof of concept. Assembly Create three identical stacked layers, each containing: A rectangular shelf frame Four independent sliding rails Four removable rubber can holders A flat snack storage base beneath the rails Layers are connected by four corner pillars. Keep the front open for access. Ignore insulation, electronics, doors, lighting, and exterior styling. Overall Dimensions Width: 300 mm Depth: 320 mm Height: 450 mm Vertical spacing between layers: 130 mm Shelf Frame Size: 300 × 320 × 15 mm Includes left and right guide channels for sliding rails Use simple plastic-on-plastic grooves (no bearings or telescopic slides) Sliding Rail Four rails per layer Length: 260 mm Cross-section: 20 × 20 mm Travel: 180 mm Include front and rear stops Each rail slides independently and is removable Can Holder Attach a removable TPU/rubber C-shaped clip to the front of each rail. Requirements: Holds the can only by its upper rim Can hangs vertically without bottom support Soft clip flexes ~2 mm to fit 52–68 mm diameter cans Suitable for standard 330–355 ml beverage cans Snap-fit replacement design for easy swapping Storage Layout One rail holds one can Four rails per layer Three layers total 12-can MVP capacity Flat platform below each layer stores snacks such as chocolates, cookies and chips Layer Connection Four corner pillars: 15 × 15 × 130 mm Simple screw or snap-fit assembly Manufacturing Body: PLA or PETG Clip: TPU (food-grade preferred) Wall thickness: 3 mm minimum Fillets: 2 mm minimum Avoid overhangs above 45° Optimised for FDM 3D printing Constraints No springs No bearings No telescopic drawer slides No metal parts No unnecessary cosmetic details Keep the mechanism simple, reliable and easy to manufacture Deliverables Generate: Fully constrained parametric CAD assembly Individual part files Exploded view Section view Motion showing independent rail sliding Bill of Materials (BOM) Editable dimensions as parameters
