A 3D-printable QR code

A QR code you can hold. Text in, a raised-module STL out, and it must actually scan when printed.

Requirements

Encode any text as a QR code with error correction level configurable

Generate a solid: a base plate and raised modules, with a quiet zone

Module size, height and plate margin configurable, with defaults that scan from a phone at arm's length

Export STL, 3MF and OBJ

Verify in code that the generated pattern decodes back to the input

A two-colour variant: modules and base as separate bodies
