The prompt
Create a parametric multi-body CAD assembly of a 360-degree rotating LiDAR mechanical package. Units: mm. Z axis is the rotation axis, Z=0 is the bottom of the base. Build each part as a separate named solid body, then assemble them coaxially at the Z positions given. Overall assembly: 110 mm max diameter, 100 mm tall. FIXED PARTS 1. Base_Housing: cylinder OD 110, height 30, wall 3, floor 4 thick (floor top at Z=4). Four M4 through-holes on a 95 mm bolt circle in the floor. Rectangular connector cutout 20 x 12 on the side wall near the bottom. Top rim has an O-ring groove 2.5 wide x 2 deep at diameter 100. 2. Bearing_Tube: central tube fixed to base floor, OD 36, ID 28, Z=4 to Z=60. 3. Main_PCB: annular plate OD 96, ID 38, thickness 1.6, at Z=4 to 5.6, around the tube. 4. Slip_Ring: cylinder OD 22, height 20, Z=4 to 24, inside the tube, with 12 wires out of the bottom. 5. Motor_Stator: ring ID 38, OD 60, height 10, Z=20 to 30, mounted on the outside of the tube, with visible copper windings. 6. Optical_Window: clear cylinder OD 100, wall 2.5, height 60, Z=30 to 90, bottom flange seated on the base O-ring groove. 7. Top_Cap: disc OD 100, thickness 10, Z=90 to 100, with a 3 mm recess on the underside for the window rim, 4x M3 screw holes on an 88 mm bolt circle. 8. Encoder_Sensor: block 8 x 6 x 4 on the tube wall at Z=34 to 37. ROTATING PARTS 9. Shaft: hollow, OD 12, ID 6, length 46, Z=24 to 70. 10. Bearing_A: deep-groove ball bearing 6001 (bore 12, OD 28, width 8) at Z=26 to 34, between shaft and tube. 11. Bearing_B: same 6001 bearing at Z=50 to 58. 12. Spacer_Sleeve: OD 20, ID 12, Z=37 to 50, on the shaft between the bearings. 13. Encoder_Ring: magnetic ring OD 20, ID 12, thickness 3, Z=34 to 37, on the shaft. 14. Rotor_Magnet_Ring: ID 62, OD 68, height 10, Z=20 to 30, around the stator. 15. Rotor_Skirt: thin cylinder OD 68, wall 3, Z=20 to 60, connecting the magnet ring up to the platform. 16. Rotor_Platform: disc OD 80, thickness 8, Z=60 to 68, central 12 mm hub bore clamped to the shaft, lightweight pockets on the underside, 6x M4 threaded balance holes on a 70 mm diameter circle. 17. Laser_Module: block 20 x 20 x 20 with a 20 mm diameter beam aperture, 905 nm pulsed laser, Z=68 to 88, at X=-25, facing +Y. 18. Receiver_Module: APD receiver block 25 x 25 x 20 with a 25 mm diameter lens, Z=68 to 88, at X=+25, facing +Y. 19. Scan_Mirror: flat front-surface mirror 35 x 35 x 3, in a black aluminium holder, tilted 45 degrees, centered at Y=35, Z=78. CONSTRAINTS All rotating parts coaxial on the Z axis. No interference between rotating and fixed parts, with at least 1 mm radial clearance between the rotor skirt and base wall and between the rotating assembly and the window. Show assembly in isometric view and also an exploded view along Z with part labels.
