About this gig

Need a 3D model that you can actually print not just something that looks good on screen?


A model can look perfect in CAD and still fail during printing because of incorrect dimensions, poor wall thickness, bad clearances, unsuitable geometry, or parts that don't fit together.


I design 3D printable STL and CAD models for prototypes, replacement parts, functional components, custom products, and mechanical projects.


What I Can Design

  • 3D printable parts
  • Custom replacement parts
  • Functional prototypes
  • Mechanical components
  • Product enclosures
  • Brackets & mounts
  • Custom adapters
  • Multi part assemblies
  • Existing model modifications


What You Get

  • Print ready 3D model
  • STL file
  • STEP/CAD file
  • Accurate dimensions
  • Functional clearances where required
  • Clean geometry
  • Source file according to package


I don't just convert a sketch into a random 3D shape. I'll consider how the part is intended to be used and printed, so the design is practical for your project.


Have a specific part in mind? Send me the reference and dimensions before ordering so I can confirm the complexity and recommend the right package.
