The prompt
"Design a snap-in U-shaped battery holder casing for a single 21700 battery. Create a main rectangular body with an outer length of 74 mm, outer width of 25 mm, and outer height of 15 mm. Make a horizontal cylindrical cutout along the center of the length with a diameter of 21.5 mm (includes 0.5 mm tolerance). Cut the top open so a battery can be pressed in from above. Ensure a uniform wall thickness of 2 mm. Add a 3 mm circular hole on the center of both end walls for wire contacts. All units are in millimeters
