3D Model: Create A 3D-printable, Full-body Model Of Darth Vader Standing In A Heroic Pose. He Should Have His Classic Armor And Cape, But With One Unique Twist: His Helmet Has A Subtle Smirk (not Exaggerated, Just A Slight Smile). The Model Must Be Manifold, With No Holes Or Non-printable Overhangs. Keep Details Crisp For FDM/resin Printing, And Ensure The Cape Is Detachable Or Split For Easier Support Removal. Export As An STL Or OBJ File."
