Turn any link into a keychain with your QR code embossed on it, keyring hole already built in. Perfect for weddings, fairs, conferences, or as a keepsake with your favorite link.
Create my QR keychain →Who this is for
Couples planning a wedding who want a useful favor for guests (a link to the playlist, the photo album, or the venue map), event and conference organizers, brands handing out merch, or anyone who wants a personalized keychain with their own link.
What the 3D model includes
The keychain is generated with the QR code embossed in two colors and a circular keyring hole already built into the design — nothing to drill or add after printing. You can also add text (a name, a date) embossed below the code.
How it works
-
1
Paste the link you want on the keychain
A website, a photo album, your social profile, or any URL.
-
2
Choose "Keychain" and set size and colors
40–60 mm is usually a good size; add text if you like.

Download the 3MF, print, and add the ring
The hole is already in the model — just thread the ring through.
Frequently asked questions
Does the keychain already come with the ring hole?
Yes, the "Keychain" format includes a circular hole at the top, built directly into the 3D model — no need to drill it after printing.
What keychain size do you recommend?
40–60 mm is usually a good balance between QR readability and a manageable keychain size. The tool warns you if the QR module size gets too small to scan reliably.
Can I make several different keychains at once?
Each keychain is generated and downloaded individually from your browser, but since there's no usage limit you can repeat the process as many times as you need (for example, one per wedding guest).
Do I need my own 3D printer?
Not to generate the file — the tool is free. To print it, yes, you'll need a 3D printer; if you don't have one yet, we compare models here (in Spanish).
