The prompt
Create a 3D open-top box tray measuring 193mm width, 193mm length, and 55mm height with 3.5mm outer wall thickness and a solid 3.0mm floor. Top face is completely open. On the interior floor, place four Mini-ITX motherboard standoffs (height 6mm, spacing 157.5mm x 154.9mm with M3 screw holes). On the right wall, add an 80mm cooling fan port (76mm circle cutout with 71.5mm x 71.5mm M4 mounting holes). On the rear wall, make a 158.75mm x 44.45mm I/O shield cutout. At the four floor corners and four top-rim corner pillars, add 4.2mm M4 screw alignment holes for vertical module stacking.
