Xiaomi/Roborock LDS02RR LiDAR Mounting Bracket

Create a precise 3D-printable mounting bracket for a Xiaomi/Roborock LDS02RR LiDAR sensor. Use millimeters for every dimension. The LiDAR body is approximately circular, but it has four external mounting tabs / screw locations around the perimeter. Design the bracket as a round or rounded mounting base that follows the general footprint of the LiDAR, with four reinforced mounting areas corresponding to the LiDAR screw locations. The screw-hole pattern must be treated as a symmetrical trapezoidal pattern, not as a rectangle. Use these exact measured center-to-center dimensions: - Distance between the two upper mounting holes: 60 mm - Distance between the two lower mounting holes: 49 mm - Vertical distance between the upper row and lower row: 80 mm The upper holes are farther outward than the lower holes. Assuming the mounting pattern is horizontally centered, use these precise hole-center coordinates: - Upper-left: X = -30 mm, Y = +40 mm - Upper-right: X = +30 mm, Y = +40 mm - Lower-left: X = -24.5 mm, Y = -40 mm - Lower-right: X = +24.5 mm, Y = -40 mm The upper holes therefore sit 5.5 mm farther outward on each side compared with the lower holes. Make the mounting plate: - mechanically strong - lightweight - easy to print - printable flat on a standard FDM 3D printer - no supports required Use a base thickness of 4 mm. Create reinforced circular bosses around each screw hole, approximately 10 to 12 mm in outer diameter, so the mounting tabs are strong enough for repeated assembly. Use 3.5 mm diameter holes initially, suitable for M3-class screws with printing clearance. Keep enough material around every screw hole to prevent cracking. The central region should support the LiDAR body but should not interfere with the rotating upper part, motor, belt, electronics, connector, or wiring. Leave the LiDAR's rotating turret completely unobstructed. The mounting bracket should support the LiDAR from underneath. Do not create walls higher than the LiDAR base unless necessary. Add rounded external edges and fillets where practical. Make the following dimensions fully parametric and editable: - upper hole spacing = 60 mm - lower hole spacing = 49 mm - vertical hole spacing = 80 mm - screw hole diameter - plate thickness - outer diameter / footprint of the support - mounting boss diameter The mounting hole positions are the most important part of the model. Do not approximate or automatically relocate the mounting holes. Generate a clean watertight CAD solid suitable for export as STL and STEP.
