The prompt
Create a 3D printable keychain based on the reference image I uploaded. **EXACT DIMENSIONS:** - Main keychain body: 50 mm wide × 50 mm tall. - The entire keychain must fit within a 50 × 50 mm area. - The top attachment tab and its hole must be included within these dimensions. **DESIGN:** - Reproduce the uploaded image on the front surface. - Add one straight, centered rectangular tab at the TOP. - The tab must be aligned with the image and connected directly to the body. - Add one circular hole for a keyring. - Do not add a separate ring or chain. - Keep the original image recognizable and preserve its proportions. - Flat front and back surfaces. - Solid, durable and suitable for PLA 3D printing. - Create one single connected 3D model. Export as a watertight STL file ready for 3D printing. Do not exceed 50 × 50 mm in overall dimensions.
