3D Print QR Code Generator (Solids)

About this generator

3D Print QR Code Generator turns a link or a piece of text into a printable QR tag. You type the content, pick a size, set the base plate and QR heights, click Generate and export an STL. It runs in the browser and is made by the team behind Solids, a free browser CAD app.

The size presets are 25, 32 and 50 mm, or a custom size. The QR can be raised, or embossed into the plate with a negative QR height. More settings add a keychain hole on the left, top or corner, a text label on a connected tab so the export stays one piece, a center icon, an inverted QR and a corner radius. The FAQ suggests a 32 mm plate, a 2 mm base and a QR height of about 0.8 mm, and notes that shorter text scans more reliably on small tags.

It is free and needs no account. The export is a single STL, so a second color means a filament change at the layer where the code starts. The site has no terms or license text and says nothing about selling prints. It suits anyone making a Wi-Fi tag, a link keychain or a small QR sign.
