The prompt
A detailed 3D CAD model of a desktop CNC router machine, 400mm x 300mm x 70mm working area, mechanical design style. The frame is constructed from black anodized 2080 and 2040 aluminum extrusions with a silver aluminum T-slot bed. The Y-axis has a dual-motor setup with two NEMA 23 stepper motors mounted at the rear, driving 8mm lead screws on both sides. The gantry is supported by two custom upright aluminum gantry plates shaped like Stepcraft CNC plates (curved, vertical side plates). The X-axis and Z-axis use SC12UU linear bearing blocks sliding on 12mm silver steel linear rods, driven by 8mm lead screws with brass anti-backlash nuts. A silver 800W air-cooled spindle with an ER11 collet is mounted on the Z-axis carriage. Clean cable management with black drag chains on X and Y axes. Professional engineering render, high detail, industrial design, isometric view. make it a frecad model so it can be edited
