3D QR Maker

Turn a link into a QR plaque you can 3D print, as 3MF or STL. You get a white plate with the QR code raised in black, sized in millimetres.

Start from the P2S reference size: 76.2 × 76.2 mm and 4.4 mm thick, known to print well on a P2S with a 0.4 mm nozzle at 0.20 mm layers.

Destination URLText above the QR code (optional)Raised in black in a blocky font that prints cleanly. Up to 18 characters.Center icon (optional)Switches the QR code to high error correction and keeps a white area around the raised mark.

Filament labels

The 3MF carries the full settings for each filament: temperature, flow, cooling, wipe and retraction, and volumetric speed. These names only label them in Bambu Studio, so they don’t need to match a preset you have installed.

White basePLA-Basic: 220 °C, flow 0.98, up to 21 mm³/s.Black topePLA-Lite: 210 °C, flow 0.98, up to 12 mm³/s, extra wipe and retraction.

The 2.0 mm quiet border is about 1.5 modules wide. The QR standard asks for 4.

3MF is one printable mesh with the QR surfaces painted black for Bambu Studio. STL has no color, so add a filament change where the raised layer begins.
