Generate the actual QR module matrix locally and turn it into a raised or engraved, mirrored-optional, closed STL sign with selectable error correction and physical module-size feedback.
Physical QR signs are useful for menus, Wi-Fi instructions, product displays, exhibits, and maker projects. This tool goes directly from payload to printable relief while keeping the destination text local.
The browser generates the QR module matrix locally with the selected error correction, preserves the quiet zone, builds an aspect-correct relief field, reports approximate physical module size, and exports binary STL.
No. The payload is encoded but never opened or verified.
Choose raised or recessed modules. Contrast still depends on the physical material, paint, lighting, and print quality.
