Make a QR code people can scan and print

A QR code that works on a screen can fail after printing because its modules are too small, its colours are too similar, or its quiet zone has been crowded by a border. The maker calculates the printed module size from the payload, token size, padding, shape, and caption before export.

The default four-module quiet zone follows the conventional QR layout. A compact two-module option is available for constrained designs, but the preflight presents it as a deliberate risk rather than silently shrinking the code.

Enter the payload first because longer text produces a denser QR matrix. Choose raised or flush detail, use a light base with dark modules, and apply the recommended minimum token size when the preflight requests it. Download the 2D reference and scan it with more than one phone before committing to a long print.

For Wi-Fi tokens, test the exact network name, password, security mode, and hidden-network setting. For contact tokens, keep only fields that recipients actually need; a smaller payload usually produces larger, more forgiving modules.

Use STL for a single mesh or 3MF when you want separate base and detail filament assignments in Bambu Studio. Geometry is generated locally in the browser, so Wi-Fi passwords and contact information are not uploaded to 1ClickMade.
