ATX Computer Chassis Frame

​Create a rectangular computer chassis frame, 245 mm wide, 540 mm high, and 530 mm deep, with a wall thickness of 3 mm. Add a 220 mm wide by 86 mm high cutout at the bottom rear for a power supply. Add a 146 mm wide by 42 mm high rectangular hole at the top front for an optical drive. Add a 420 mm by 140 mm rectangular cutout centered on the top panel, and a 420 mm by 140 mm rectangular cutout centered on the front panel. Add a 140 mm high by 62 mm wide cutout on the rear panel for PCIe slots. ​Workflow Tips for Text-to-CAD ​Generate and Measure: Always measure critical features after exporting the STEP file, as the AI's output is a starting draft, not a finished production part. ​Tune Parameters: If using a platform with an editor (like TextoCAD or Zoo's Zookeeper), use the provided sliders to refine the exact millimeter dimensions if the initial generation slightly misses your radiator or PSU clearances. ​Iterate Single Parts: If the full chassis frame proves too complex for the AI to render accurately, break it down. Generate the flat panels, motherboard tray, and PSU shroud as separate, simpler prompts, then assemble the exported STEP files manually in standard CAD software.

Parameters

Every value above is a live dimension. Open a model like this in the editor and each one becomes a slider you can drag before exporting.
