About this gig

Hi, I'm Hanna, a Germany-based 3D product designer with 6 years of professional experience. I design functional mechanical parts for 3D printing, from simple replacement components to detailed prototype parts and multi-part assemblies. I solve common printing problems such as poor fit, incorrect clearances, weak geometry and models that are not properly prepared for production. My approach combines mechanical CAD design, practical tolerances and print-ready modeling for reliable results.


What I offer

  • Functional mechanical part design
  • 3D printing & CAD modeling
  • Print-ready STL & 3MF files
  • STEP files for editable CAD
  • Fit, clearance & tolerance planning
  • FDM and resin-ready geometry
  • Prototyping & replacement parts
  • Basic and complex mechanical assemblies
  • Print orientation & support considerations
  • adjustments for existing models


Why choose me

  • 6 years of professional CAD experience
  • Mechanical engineering-focused design
  • Accurate, clean & editable models
  • Fast and reliable delivery
  • Clear communication and attention to detail


Get a functional 3D print design built around your part, fit and intended use not just a model that looks correct on screen.

Delivery style preference

Please inform the freelancer of any preferences or concerns regarding the use of AI tools in the completion and/or delivery of your order.
