About this gig

A great 3D print starts with a model designed for the way it will be printed.


I provide 3D printing de-sign, 3D modeling, STL design, CAD modeling, 3D printable parts, and prototype design for inventors, makers, engineers, startups, and businesses.


Send me your sketch, dimensions, reference image, existing STL, STEP file, or basic concept. I can create or modify the 3D CAD model based on your requirements and intended printing method.


My services include:

  • 3D Printing De-sign
  • STL File Design
  • 3D Modeling
  • CAD Design
  • 3D Printable Models
  • 3D Printable Parts
  • Prototype Modeling
  • Mechanical 3D Modeling
  • STL & STEP Files
  • CAD File Modification
  • Print-Ready 3D Models
  • Functional & Replacement Parts


I can design brackets, housings, enclosures, mounts, adapters, mechanical components, custom parts, prototypes, and other 3D printing models.


I focus on accurate dimensions, proper clearances, tolerances, wall thickness, clean geometry, and practical print preparation.


Have an existing STL or CAD file that needs changes? I can adjust dimensions, update features, repair geometry, or prepare the model for 3D printing.


Send your files or project details and let's get started.
