Basic 3D Model from Logo

I need a 3D model created from my logo image to make a keychain for 3D printing.

The final model should look similar to the attached example image (raised logo on a solid base with a keyring hole).

Requirements:

• Convert my logo PNG into a 3D printable STL file
• Add a solid base layer behind the logo
• The logo should be raised above the base
• Add a keychain loop with hole for a keyring
• Everything must be one solid printable object
• Must be optimized for FDM 3D printing

Color / layer setup:

• The bottom/base layer should print in black
• The top raised logo should print in grey
• Design the model so it is ready to import into Bambu Studio for two-color printing
• Base layer thickness can be increased if needed for strength

Specifications:

• Width: about 70 mm
• Base thickness: 2–3 mm (can increase if needed)
• Raised logo height: ~1 mm
• Keyring hole: 5 mm

Important:

• Do not change the logo design
• Just convert it into a clean 3D printable keychain model

Deliverables:

• STL file ready for 3D printing
• Optional: STEP or source CAD file
