QR code generator for 3D printing
Paste your link, pick two colors and download it as an image or as a two-color 3D object ready to slice: keychain, table stand or wall plaque. Free, no sign-up.
How it works, in 3 steps
- 1
Paste your link
Your menu, your Google listing, your Instagram or the shop wifi. The code is drawn instantly as you type.
- 2
Make it yours
Pick the dot shape, the two colors and, if you like, your logo or an emoji in the center. The 3D view updates on its own.

Download and print
PNG or SVG for screen and paper, or the 3MF file with both colors already inside, ready to drop into your slicer.

A 3D printed QR code lasts as long as the business does
A QR code taped on paper gets wet, peels off and ends up creased under a glass. 3D printed, it becomes a solid object you wipe clean with a cloth, one that survives a busy table and doesn't blow away under the air conditioning. That's the difference between a sign you reprint every month and a piece that belongs in the room.
What makes it work isn't the styling, it's the contrast. A phone camera has to clearly separate the dark squares from the light background, and on a printed part that only happens with two different filament colors. That's why this generator exports a 3MF file instead of the classic STL: 3MF stores each part's color inside the file, so opening it in Bambu Studio, PrusaSlicer, Orca or Cura shows the base and the code already separated with their colors assigned. With STL you'd get two loose, colorless files to line up by hand.
What to check before you hit print
Module size — the size of each little square in the code — matters more than anything else. Below 1.5 mm the nozzle rounds the corners, neighboring squares merge and the pattern stops scanning even though it looks fine to the eye. Since the number of modules depends on how many characters your link has, a long URL forces a bigger part. If your link is enormous, shorten it first: you'll get chunkier modules and a much cleaner print. The tool measures this live and turns it red when it falls short.
Keep the relief height between 1 and 2 mm; 1.2 mm is the sweet spot, enough for a clean color change without stretching the print time. And if you add a logo in the center, remember it covers modules: we automatically raise error correction to the maximum to compensate, but scan the preview with your phone before running off fifty keychains.
Three objects, three situations
The table stand is deliberately tilted so it prints without supports and so the code faces a seated customer: it's the format for digital menus and for the "leave us a review" piece by the register. The keychain has a hole for the ring and works as an event giveaway or as a business card nobody throws out. The wall plaque, with two hanging holes, is the one that ends up on the wall of a vacation rental holding the wifi details, or on a trade show booth.
The whole process — generating the code, computing the relief, assembling the 3D file — happens inside your browser. No account to create, no server receiving your link, no download limit.
