Convert AI Designs to 3MF -- 2

I have a collection of AI-generated artwork that must be transformed into clean, watertight 3MF files I can forward straight to my 3D-printing partner. The finished models have to keep the exact look and colour palette of the originals while fitting inside a standard 6 × 4-inch picture frame. I’m after a smooth surface finish, so please avoid visible faceting or unnecessary texture maps.

You’ll receive the source images plus colour references the moment we start. I need each design modelled, checked for manifold issues, and oriented for print. Feel free to work in Blender, Fusion 360, SolidWorks or whichever package you prefer, as long as the exported 3MF loads without repair prompts in common slicers such as Cura or PrusaSlicer.

My timeline is tight—ASAP—so let me know how many designs you can deliver in the first pass and your typical turnaround per file.

Deliverables:
• One error-free 3MF per design, scaled to fit 6 × 4 in.
• Correct colour assignments embedded.
• Smooth surfaces, no non-manifold edges or intersecting geometry.

If you have sample 3MFs or a short note on similar work, it will speed up selection. Looking forward to working with you on this quick conversion project.
