Rpi4 tray

The request

Make a mounting tray for a Raspberry Pi 4. A 65 mm by 56 mm plate, 3 mm thick, lying flat in the XY plane, centred on the origin with Z up and its 65 mm side along X. Four standoffs stand on the top face at the Pi's hole pattern, X = ±29 and Y = ±24.5: each standoff is a 6 mm diameter cylinder 5 mm tall, with a 2.7 mm hole running down through the standoff and the plate. Cut a notch for the USB ports out of the +X edge of the plate: 20 mm wide centred on Y = 0, 6 mm deep into the plate. Name the sub-part exactly `tray`.

What the AI judge checks

• A flat rectangular plate, longer along one axis than the other
• Four short round standoffs standing up from the plate near its corners
• Each standoff has a hole down its centre
• A rectangular notch cut into the middle of one short edge
• Nothing else on the plate

Measured checks

• one sub-part named tray (gate)
• footprint is 65 × 56 and 8 mm tall with standoffs
• hole at (29, 24.5) is 2.7 mm through plate and standoff (gate)
• hole at (29, -24.5) is 2.7 mm through plate and standoff (gate)
• hole at (-29, 24.5) is 2.7 mm through plate and standoff (gate)
• hole at (-29, -24.5) is 2.7 mm through plate and standoff (gate)
• standoff at (29, 24.5) is 6 mm × 5 mm
• standoff at (29, -24.5) is 6 mm × 5 mm
• standoff at (-29, 24.5) is 6 mm × 5 mm
• standoff at (-29, -24.5) is 6 mm × 5 mm
• USB notch is clear: 20 wide, 6 deep at the +X edge
• plate is solid beside the notch
