I need a detailed SolidWorks model of an EV battery bottom tray that will be manufactured in a composite material and rated for a lightweight load—no more than 50 kg including cells, wiring, and fasteners. The design must: • Integrate standard mounting points for most skateboard-style chassis (I will share hole spacing once the project starts). • Incorporate basic airflow channels or vent openings so the composite skin can release heat without adding fans or metallic heat sinks. • Keep overall wall thicknesses and rib patterns friendly to compression-molded or vacuum-infused manufacturing. Deliverables 1. Native SolidWorks part/assembly file (.SLDPRT / .SLDASM) with fully defined features and no unresolved references. 2. A STEP file for cross-platform review. 3. One PDF drawing showing key dimensions, material callouts, and assembly notes. I will run a quick FEA pass on my side, so please leave the study set-up intact in the model even if you do not solve it. Acceptance is complete when the files import without errors and match the load and material criteria outlined above.
