Prompt
Create a clean, CAD-like 3D model of a robot chassis suitable for a 4WD soccer robot. Units: millimeters (mm). Overall footprint: 250mm x 250mm. Main base plate: 250 x 250 x 4mm, corner fillets R10. Add side walls: 3mm thick walls around the perimeter, wall height 25mm. Single solid part, manifold/watertight. No text, no logo, no textures. Wheels (assumed): wheel diameter 65mm, wheel width 26mm. Goal: wheels are slightly tucked inside the body AND the top half of each wheel is covered by the chassis (wheel arch), so about half of each wheel is outside and can rotate freely. Wheel openings / arches: - Create 4 wheel-arch cutouts on the side walls (left and right), two per side (front and rear). - The wheel arch shape: a circular/rounded arch matching a 65mm wheel, leaving the TOP half inside the chassis and the LOWER half outside. - Provide clearance: at least 3mm gap around the wheel (arch radius = 65/2 + 3 = 35.5mm). - The arch opening should extend downward so that the wheel can protrude outside and spin freely. Wheel positions (motor axes) - motors INSIDE: - Front-Left wheel/motor axis: (x=55mm, y=180mm) - Rear-Left wheel/motor axis: (x=55mm, y=70mm) - Front-Right wheel/motor axis: (x=195mm, y=180mm) - Rear-Right wheel/motor axis: (x=195mm, y=70mm) Motor mounting pattern for each 37mm geared DC motor (inside mounting): - At each motor axis, add a 12mm diameter center shaft clearance hole. - Add two M4 through-holes (diameter 4.2mm) aligned horizontally with the motor axis: - hole centers at (motor_x - 12mm, motor_y) and (motor_x + 12mm, motor_y) - 24mm center-to-center spacing. - Add a flat mounting pad area around each motor: 50mm diameter, blended with fillets R2 (still one solid part). Electronics mounting: - Add 4 M3 through-holes (3.2mm) for standoffs, 15mm from edges near each corner. Ensure: - Wheel arches line up with the wheel/motor axes. - Wheels are tucked inside by having the side walls slightly outside the wheel centerline, but keep enough opening so the wheel can rotate without rubbing. - Output as a single solid chassis ready for fabrication. Units: millimeters. Plate: 250mm x 250mm square, thickness 4mm, corner fillets R10. Single solid part, manifold/watertight. No text, no logos, no textures, no extra objects. Motor mounting (2 motors, 37mm geared DC motor): - Add two identical motor mounting patterns, symmetric left and right. - Motor axis positions: (x=70mm, y=125mm) and (x=180mm, y=125mm). - For EACH motor pattern: - 4 through-holes for M4 screws (hole diameter 4.2mm). - Hole center-to-center spacing: 24mm horizontally (X) and 30mm vertically (Y) around the motor axis. - Add a central shaft clearance hole: 12mm diameter at the motor axis. Extra mounting: - Add 8 through-holes for M3 (3.2mm) near corners for standoffs: - Place each hole 15mm from the nearest two edges (two holes per corner zone, symmetric). Output: one solid printable base plate.
