Free 3D QR Code Generator — Turn Any Link into a Print-Ready 3D Model

Create a custom, scannable QR code and export it as a print-ready 3D model in seconds. Paste a link, Wi-Fi login, email, or phone number, style the code with your own colors and module shapes, then download a full-color 3MF, OBJ, or STL file for your 3D printer. Choose whether the code stands proud of the base or sits flush as a smooth two-color tile, set the exact size in millimeters, pick a square, rounded, or circular outline, add a hanging hole, or turn it into a desk stand. Everything runs 100% in your browser — no signup, no watermark, no upload.

How to Make a 3D QR Code

1. Pick what your QR code should do: open a link, share Wi-Fi, start an email, or dial a phone number.
2. Style the code: square, rounded, or dot modules and your own foreground and background colors.
3. Pick a 3D profile: raised code on a backing plate, or a flat two-color tile.
4. Set the width, base thickness, border, and outline shape (square, rounded, or circle).
5. Add a hanging hole for a keychain, turn it into a desk stand, or wrap it in a "SCAN ME" frame with your own label.
6. Scan the live preview with your phone to confirm it works, then download 3MF, OBJ, or STL.

Full Color, Mapped for Multi-Material Printing

The 3MF and OBJ exports carry each color as a separate material, so when you open the file in Bambu Studio, OrcaSlicer, or PrusaSlicer the foreground and background colors are ready to assign to your AMS or multi-material unit. On a single-nozzle printer you can print the raised profile and swap filament at the base height, or print the flat tile with a color change on the top layers. The STL export is a single solid for classic one-color printing.

Raised or Flat — You Decide

• Raised: the code stands up off a solid backing plate. Set exactly how far it sticks out. Great for tactile signs, tags, and coasters.
• Flat: a smooth two-color chip where the code is level with the surface. Perfect for cards, keychains, and inlays.
• Any outline: square, rounded-corner, or a round coin/token shape.
• Backing control: adjust base thickness, or make it a thin flat chip in the shape of your choice.
• Hanging hole: add a keyring tab and hole above the code to turn it into a keychain or wall tag.
• Desk stand: turn it into a self-standing display with an angled base for a counter, shelf, or table.
• "SCAN ME" frame: add a bordered frame with a labeled banner (bottom or top) and your own call-to-action text to boost scans.

Popular Uses

Recommended Print Settings

• Layer height: 0.12–0.20 mm for crisp code edges
• Keep module size at or above 1.2 mm so the code stays scannable
• Use strong contrast (dark code, light background) for reliable scanning
• Raised profile: print base-down, no supports needed
• Flat profile: print flat on the bed; change color at the top layers on a single nozzle
• Stand: prints flat-bottom with the angled brace, no supports needed
• Multi-color: assign the 3MF/OBJ colors to your AMS or MMU filaments

Frequently Asked Questions

Will the 3D printed QR code actually scan?

Yes. Print with good contrast between the code and background colors, keep the module size at 1.2 mm or larger, and keep a light border (quiet zone) around the code. Test the live preview on this page with your phone before printing.

Can I make it stand up on a desk?

Yes. Turn on Make it a stand and the code is tipped upright and given an angled base so it stands on its own on a counter, shelf, or table — no separate holder needed. It prints flat-bottom with no supports.

Can I add a "SCAN ME" frame?

Yes. Turn on the frame to wrap the code in a border with a labeled banner. Type any call to action ("SCAN ME", "MENU", "REVIEW US", "WIFI") and choose whether the banner sits at the bottom or top. The label prints in your background color so the code stays scannable, and it works with the raised, flat, and stand options.

What file formats can I download?

3MF (recommended, full color in one file), OBJ (with a color material file), and STL (single-color solid). 3MF and OBJ preserve the code and background colors for multi-material printing.

What is the difference between raised and flat?

Raised makes the code stand up off a backing plate, and you control exactly how far it sticks out. Flat makes a smooth two-color tile where the code is level with the surface — ideal for cards and inlays.

Is this QR code generator free?

Yes. It is 100% free with unlimited downloads, no account, and no watermark. Everything is generated privately in your browser — your links are never uploaded to a server.

Can I make a round QR code coin?

Yes. Choose the circle outline to make a round coin or token, pick raised or flat, add a hanging hole, and download it ready to print.
