What is the 3D Text & QR Code STL Generator?
The text tab turns any text into raised 3D lettering using real outline fonts, with the letter height, thickness and a choice of base — none (separate letters), rectangle, rounded plate or a keychain plate with a ring hole. The QR tab encodes any text or URL (including Wi-Fi strings or contact cards) into a printable QR plate: pick the error-correction level, the size of each module in millimetres, the height of the raised code, the quiet zone and the plate thickness; you can raise the light modules instead of the dark ones for the opposite polarity.
Both tabs preview the result in 3D with size and volume, and export STL or 3MF. For a scannable code, print it flat with the code facing up, in contrasting colours — for example a white plate and a black raised code made with a filament change at the code layer — and test it with a phone before using it.
