What is QRCode2STL?

QRCode2STL is a long-running, open-source web app for 3D-printable codes. It creates standard QR codes for text and URLs, WiFi logins, email, vCard contacts, SMS and calendar events, and it can also build Spotify codes or plain text tags.

The 3D options are thorough: rectangle or rounded base, border, a custom title, a keychain hole, an indentation for an NFC or RFID tag, magnet pockets, inverted codes, adjustable block size and a randomised QR-City height effect. Batch mode handles many codes at once, and you can export the base and code as separate parts for color swaps, as binary or ASCII STL. A built-in guide explains single-extruder color changes.

It runs free in the browser with no account, and the source is on GitHub under the MIT license. It suits WiFi signs, keychains and business tags.
