About this gig

Model won't print? Mesh full of errors? Wrong file format? A single mesh that needs splitting into parts? Don't worry, you're at the right place


I fix, convert, and restructure existing 3D car models so they actually work for your intended use.


SERVICES:


  • Format conversion (OBJ, FBX, STL, STEP)
  • Mesh repair and geometry cleanup
  • Retopology
  • STL repair for printing
  • Hollowing where appropriate
  • Part separation
  • Model optimization


PART SEPARATION: (a core specialty)


  • Body, wheels, windows, interior
  • Bumpers, lights, mirrors, trim
  • Split logically for painting, multi-color printing, or assembly


3D PRINT PREPARATION:


  • Watertight, closed geometry
  • Correct wall thickness
  • No bad intersections or overlaps
  • Print-bed size factored into splits
  • Assembly interfaces that actually fit


FILE FORMATS:


  • STL, 3MF, OBJ, FBX
  • STEP where technically appropriate


HOW IT WORKS:

Send me your existing model, desired output, which parts need separating, scale/dimensions, and your target software or printer. I'll assess the file and confirm scope.


If your model's complexity is unclear, send it over before ordering so I can confirm the right package. FAQ below covers the most common questions.


Thanks!

I’m Simon, an automotive 3D modeler with 7+ years of experience creating accurate car exteriors, interiors, printable parts, and detailed scale replicas. I build clean, production ready 3D assets for visualization, games, configurators, digital collectibles, and 3D printing, working from photos, blueprints, and technical references. My workflow covers reference-based modeling, mesh repair, retopology, UV mapping, texturing, part separation, and format conversion between OBJ, FBX, and STL. I focus on precise proportions, clean topology, logical assemblies, and reliable file delivery.
