Test it now. This is the exact code that will be printed. Point a phone or a scanner at it — if it reads the right thing here, it will on the plate.
What you get. 2 mm plates (3 mm with magnet pockets) with rounded corners; the lettering and the QR are 1 mm inlays in a second color — they can't rub off, fade or smudge. Screw holes are cut to the M3 / M4 / M5 clearance you pick plus 0.2 mm for the printer; countersinks take flat-head screws flush. Magnet pockets fit 10 × 3 mm discs (not included). The hanging hole on tags takes a bead chain, wire or zip tie; cable tags take two standard zip ties. Outdoor-rated PETG on request — ask.
