About this gig

Is your 3D model non-manifold, full of holes, or failing to slice correctly? I will fix your broken STL/OBJ files and optimize them specifically for flawless 3D printing.

Using professional CAD software, mesh repair tools, and slicers (Orca Slicer, Fusion 360, SolidWorks), I resolve complex mesh errors while preserving precise geometry.

Services I offer in this Gig:

Mesh Repair & Healing: Fixing holes, non-manifold edges, inverted normals, self-intersections, and bad facets.

3D Print Optimization (DFAM): Wall-thickness verification, hollow design with drain holes, overhang checks, and support placement strategy.

Model Splitting & Alignment: Cutting large models into interlocking parts with registration pins for easier printing and assembly.

Scale & Unit Correction: Fixing distorted scaling (inches/mm/meters) and aligning orientation to fit printer build plates.

Why work with me?

Practical 3D Printing Expertise: I operate actual 3D printers and test slicer profiles daily no guesswork.

Printability Guarantee: Every repaired file is verified inside slicer software before delivery.

*Please message me your file before ordering so I can analyze the mesh damage and give you an instant quo
