baby footprint 3d model

Create two realistic baby footprints, one left foot and one right foot, designed as a flat 3D relief for a keychain. Each footprint should have five clearly defined toes and a natural baby foot shape. Keep the bottom completely flat and the top surface smooth. The footprints should be separate from each other, with no background, no text, and no additional objects. Make the model suitable for FDM 3D printing with a 0.4 mm nozzle. Use clean, simple geometry with no very thin or fragile parts. The final model should be easy to scale to approximately 15 mm in height per footprint and suitable for exporting as STL or 3MF.
