The prompt
Create a compact mechanical counter housing for a 3D printed rosary counter. Approximate overall dimensions: 70 mm long, 40 mm wide and 12 mm thick. These dimensions are flexible. The model may be slightly larger or smaller if needed to accommodate the mechanical components. Prioritize a compact design and functional geometry over exact dimensions. The housing contains two separate rotating cylindrical number wheels placed side by side. Wheel A has 10 equally spaced positions numbered 1 to 10. Wheel B has 5 equally spaced positions numbered 1 to 5. Each wheel rotates around a central axle. Add a small rectangular viewing window above each wheel to display one number at a time. Add one push button on the side of the housing. Leave enough internal space for a simple mechanical ratchet mechanism. Use separate printable parts for the housing, two wheels, axles and button. Use simple geometry suitable for FDM 3D printing with PLA. Use approximately 0.3 mm clearance between moving parts. The housing shape, wall thickness and internal layout may be adjusted as needed. Keep the design easy to assemble and suitable for everyday handheld use. First create the housing and the two rotating numbered wheels. Do not add the automatic carry mechanism yet. Focus on a simple, printable mechanical design.
