The prompt
Create a 3D model of a gear motor assembly with the following geometric features and exact dimensions: 1. Motor Body: A horizontal cylinder with a diameter of 162mm and a length of approximately 250mm. On top of the motor body, add a square terminal box measuring 70mm x 70mm with a height of 51.5mm, offset 84.5mm from the gearbox flange. 2. Gearbox Housing: A rectangular block attached to the motor, measuring 160mm in width, 116mm in height, and 106mm in thickness. 3. Output Hollow Shaft: A hollow cylindrical shaft passing completely through the gearbox housing. The inner diameter of the bore is 30mm, and the total width of the shaft extending out is 124mm (protruding 9mm on each side of the 106mm housing). Include an internal keyway slot that is 8mm wide, with a total height from the bottom of the bore to the top of the keyway equal to 33.3mm. 4. Mounting Holes: Add 8 threaded mounting holes (M12) on the front and back faces of the gearbox flange. The holes are arranged symmetrically around the shaft axis with a vertical spacing of 96mm (48mm above and 48mm below the axis) and horizontal spacings of 91mm and 48mm from the shaft center line. All units are in millimeters. The model should be clean, manifold, and suitable for engineering use.
