When unwrapping light 3D models for 3D printing, prioritize non-overlapping UV maps—while printing relies on geometry, UVs let you preview textures (e.g., finishes, labels) before production.
UV unwrapping helps visualize surface details for light parts like shades or bases. Use tools like Blender’s "Smart UV Project" to split the model into logical UV islands (e.g., separating the shade from the base) to avoid stretching.
For beginners, start with simple designs (e.g., basic desk lamps) in Blender. Use "Smart UV Project" for initial UVs, then tweak islands to be compact—this makes texture editing easier to preview the final printed light.
