pan-tilt turret 3d model

Design a mechanical pan-tilt turret for a thermal security camera system. Requirements: The system must support a cylindrical thermal camera weighing 2 kg and approximately 200 mm long and 70 mm diameter. The turret should include two axes: - Pan axis with full 360° rotation - Tilt axis from -20° to +90° Base structure: - Square base plate 200 mm × 200 mm - Thickness 6 mm - 4 mounting holes for pole mounting (8 mm diameter) Pan system: - Lazy Susan bearing with diameter 120 mm - Pan rotating plate diameter 160 mm - NEMA23 stepper motor driving the pan axis - Timing belt drive with 4:1 reduction ratio - Motor mounted on base plate Tilt system: - U-shaped aluminum frame mounted on the pan plate - Frame width 120 mm - Frame height 100 mm - 5 mm aluminum thickness Tilt axis: - 8 mm steel shaft - two ball bearings - NEMA17 stepper motor for tilt control Camera mount: - adjustable clamp mount for cylindrical camera - centered on tilt axis for balance Additional components: - cable routing hole in center of
