Inspiration

3D printing has become more accessible than ever, yet creating even the simplest printable objects still requires CAD expertise, paid software, and hours of trial-and-error.

We noticed a pattern: People wanted quick, functional items like name tags, passes, or identifiers. But the design barrier stopped them cold.

We asked ourselves: Why does something so simple require so much technical overhead?

PrintMyCard was born from the idea that 3D printing should be as easy as filling out a form!

What it does

PrintMyCard is a web-based parametric generator that turns basic user inputs into print-ready 3MF files- instantly! No CAD skills required.

Users can:

  • Enter their name, title, contact info, and optional links
  • Add a QR code
  • Choose from predefined card styles
  • Generate single or bulk 3MF files

All geometry is generated automatically based on these inputs. No dimensions, no modeling, no software installs.

Accomplishments that we're proud of

  • Built a fully functional parametric generator from scratch
  • Achieved instant 3MF output directly in browser
  • Created a clean, intuitive UI that hides the complexity underneath
  • Designed a scalable architecture that supports bulk printing
  • Delivered a tool that genuinely lowers the barrier to 3D printing

What we learned

  • How to integrate CadQuery into a web-based workflow
  • The importance of designing for non-technical users
  • How to balance simplicity with flexibility
  • How to communicate a technical project in a clear, understandable way
  • The value of tight iteration between frontend and backend

What's next for PrintMyCard

We see PrintMyCard as the foundation for a broader ecosystem of accessible 3D printed objects!

Upcoming features we're excited about:

  • Live 3D preview in browser
  • More templates (keychains, tags, badges, tokens)
  • User accounts to save presets and bulk lists
  • Material-aware optimization (layer height, filament type, durability models)

Out long-term vision: Make 3D Printing as easy as generating a PDF.
