Free brick-style QR code maker

Printing the plate

• The plate is a flat base with the dark blocks raised on top. Print it face up, flat on the bed. It has a 4-block empty border, which scanners need.
• A QR code only scans when dark and light are clearly different. Print with a light base and swap to a dark filament at the layer where the raised blocks start (your slicer’s “change filament at layer” or “pause”). Raised blocks in one colour alone are hard to scan.
• Use a block size of 2 mm or more with a 0.4 mm nozzle. Test it with your phone before you stick it anywhere.
• The plate is its own shape and does not click onto bricks; it is a standalone tile. See print settings.
