3DMeld 3D Print QR Code Generator

About this generator

3DMeld's QR code generator turns a website link, a Wi-Fi network or a short text into a square plate with raised QR modules. For Wi-Fi you enter the network name, the security type and the password, and can mark the network as hidden. The QR code is made in your browser, and the privacy notice says the content you type is not uploaded.

There are only a few settings: the overall width from 24 to 160 mm (48 mm by default), and under Advanced settings the base thickness (1 to 5 mm) and the relief height of the modules (0.5 to 3 mm). A four-module quiet zone is added around the code. The 3D preview shows the plate in two colors and lists its size, for example 48 x 48 x 3.0 mm with 1.45 mm modules.

The download is a single STL; there is no 3MF, and the STL holds no color, so for a scannable print you change filament at the relief layer or paint the modules, as the FAQ suggests. It is free with no account. The site also has a print cost calculator, an SVG to DXF converter and a waitlist for an image-to-3D tool that is not open yet, none of which make a printable model. The terms are dated September 2026 and say nothing about selling prints. It suits anyone who wants a quick Wi-Fi or link sign without many options.
