3D Model: Create A Circular Keychain With A Diameter Of 40mm And A Thickness Of 3mm. Add A 3mm Hole At The Top-center Edge For Keyring Attachment. In The Center Of The Circle, Place The Provided 2D Image As A Raised (embossed) 3D Relief. The Embossed Image Should Rise About 0.6–1mm Above The Base Surface And Be Clearly Visible, Preserving All Recognizable Features Of The Original Image. The Edges Of The Keychain Should Be Slightly Beveled Or Rounded For Smoothness. The Base Surface Can Be Matte Or Lightly Textured For A Better Grip. The Back Side Should Remain Flat And Clean.
