A few top level notes:

• I'll be keeping the GitHub page/deployed app more updated than this Printables page.

• I'm posting this Printables page so that hopefully more people can find this tool if they're looking for something similar!

• I'm uploading a demonstration STEP model to this Printables page, but the whole point is that you use the generator to make your own :)

Why I made this:

• Couldn't find a QR code → STEP generator online

• Wanted to be able to edit the 3D model of a QR code so that I could add brand logo / font / integrate it into other 3D printed docks etc

• Fun project to learn GitHub Pages + more vibe coding stuff (coded it with Claude)

Why this is cool:

• Maybe helpful to you as well to be able to get a STEP file and not just a STL of a QR code model

• Lots of customization features:

  • You can add magnets, able to drive the magnet pattern either as inset from edges or absolute XY spacing 

  • Choose between raised-second-color (better for single nozzle machines) vs flat second color (nice with dual nozzle machines, bad for single nozzle machines)

  • Upload your own font if you want

• You can save settings (.json) for re import at a later date

• You can export a log or report a bug if something goes wrong (disclaimer that I don't know if I'll do anything with it right now)

• It nicely auto-names your exported file

• Ok here's a really cool part:

  • QR code models are inherently non manifold (if the cells are squares) since all the squares touch at sharps.

  • I implemented a toggle for "connect diagonal modules" which creates a user-adjustable bridge to desharp the corners.

  • This makes the model more robust to import and edit in CAD programs. You don't need to worry about this for 3D printing, though. 
    

    

Credit where credit is due:

• The UI and feature set is heavily inspired by this awesome QR → STL online tool I found.

• I built it all from scratch (well, with Claude), but a ton of the details like magnets, export settings, etc - those are inspired directly by the link above.
