Rpi4 tray
hard tier · create
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
Ranked by hand
One reviewer put one attempt from each model in order, best first, ties left tied.
Ordering by hand decides Human rank and Human rate on the leaderboard; it never affects Overall or Strict.
Every model's attempts
