I already have a base 3D file of Tony Stark’s Avengers Tower, but it needs a professional overhaul before I send it to the printer. The final piece will stand at least 16 inches tall, so every surface has to hold up under close inspection. What I need • Highly detailed refinement of the existing mesh • Corrected proportions to match on-screen references • Additional windows and glass façades, sharper exterior architectural accents, and a cleanly integrated Avengers “A” logo/insignia I’ll supply a folder of reference images to guide you through the exact window layouts, trim lines, and logo placement. The improved model must arrive watertight, manifold, and ready for 3D printing—STL or OBJ plus the native file you work in. Please keep wall thicknesses and overhangs printable at my target scale, and leave me room for at least two quick revision passes so everything is perfect before I queue it on my machine.
