The prompt
A flat, 2D-extruded mechanical side plate bracket with a thickness of 3mm. The part is 180mm long and has a varying width. - The front section (motor end) is a wider rounded rectangular flange measuring 55mm tall by 50mm long. - The rear section (shaft end) is a smaller rounded rectangular flange measuring 40mm tall by 40mm long. - Connecting the two is a narrower middle bridge that is 22mm tall, with large 8mm transition fillets where it meets the end flanges. Features at the front (motor end): - Add a 10mm central through-hole for the motor shaft. - Surrounding this hole, add a square-pattern bolt circle consisting of four 3mm mounting holes spaced 31mm apart horizontally and vertically. - Also, add two larger 5mm holes nearby for structural tie-rods. Features at the rear (shaft end): - Add two 5mm mounting/shaft holes aligned horizontally on the centerline, spaced 25mm apart. - Add three more 5mm holes for standoffs near the edges. Aesthetic / Details: - All sharp outer corners should have a 5mm fillet radius. - The entire part must be flat, parametric, and suitable for 3mm laser-cut acrylic. -
