The prompt
Design a 3D-printable electronics enclosure box for my underwater aquarium-cleaning robot. Dimensions: 115 mm long × 90 mm wide × 55 mm high. Design requirements: - A rectangular box with slightly rounded corners and smooth edges. - A separate removable lid secured with 4 screws. - A continuous groove for a silicone rubber gasket between the lid and the box to help prevent water leakage. - Internal mounting posts with screw holes for an Arduino Uno R3 and an L298N motor driver module. - Leave sufficient clearance for electronic components, wiring, connectors, and ventilation-free operation in a sealed enclosure. - Include cable-entry points on one side for motor wires, pump wires, and the power cable. Design these points to accept suitable waterproof cable glands. - Keep the cable-entry points above the bottom surface and away from the lid gasket. - Add mounting tabs or holes on the outside so the enclosure can be attached to the robot chassis. - Use wall thickness of approximately 3 mm and a lid thickness of approximately 3 mm. - Design the box and lid as separate 3D-printable parts with no supports required where reasonably possible. - Use PETG material for improved durability in a wet environment. - Avoid unnecessary decorative details; prioritize compactness, easy assembly, and practical functionality. Output: Generate a dimensionally accurate 3D CAD model with separate body and lid components, editable dimensions, and exportable STL files. Important: This enclosure will be used near aquarium water. The gasket, screws, cable glands, and assembled enclosure must be independently leak-tested. Do not assume the 3D-printed enclosure is waterproof simply because it has a gasket.
