The prompt
A 3D-printable mechanical pan-and-tilt mounting bracket assembly for a smart pedestal fan. The base is a vertical cylindrical collar that clamps onto a standard fan pole. Directly above the collar is a solid housing designed to hold a NEMA17 stepper motor vertically for azimuthal panning. Attached to the stepper motor shaft is a U-shaped yoke bracket. Inside this yoke is a mount for a standard hobby servo motor to control vertical tilt. The tilt mechanism connects to a sturdy top mounting plate designed to support a BLDC fan motor. Attached to the front of the yoke is a small 50x30mm rectangular sensor enclosure designed to hold a flat mmWave radar module. Attached to the rear of the main assembly is an 80x50x30mm electronics enclosure box with ventilation slits to house a microcontroller and motor drivers. The design should be modern, industrial, and optimized for FDM 3D printing with visible screw-hole mounting points and interlocking mechanical joints.
