WiFi QR Stand (3D Print with live preview)

Enter your WiFi name and password, get a 3D-printable desk stand with a scannable QR code on it.

- Live 3D preview — drag to orbit, scroll to zoom

- Downloads a print-ready .3mf: two parts, black and white, on separate filaments

- 120 × 48 × 140 mm by default, scalable 10–500%; prints upright, no supports

- Nothing is sent anywhere — the QR is generated in your browser

One HTML file, no build step. The QR encoder and the 3MF exporter are written from scratch; only three.js and Bulma load from a CDN.
