Make Your Own 3D Printed Keychain Online

3D printing isn’t just for complex prototypes or gadgets — it’s also a great way to make fun, personalized items you can use every day. One of the easiest and most practical projects is a custom keychain. With the right tool, you can design and download a printable file in just minutes, no CAD skills required.

In this guide, we’ll show you how to make your own 3D printed keychain online, step by step.

Why Make a 3D Printed Keychain?

  • Personalization – Add your name, initials, slogan, or logo.
  • Practicality – A lightweight, durable tag you can carry anywhere.
  • Gift-worthy – Quick to design, great for friends, coworkers, or events.
  • Fast printing – Most keychains take less than an hour to print on a standard 3D printer.

The Tool You’ll Need

Instead of struggling with CAD software, you can use a free online tool: 3D Chant Print Tool.

This tool lets you:

  • Type in your custom text or slogan.
  • Choose fonts, styles, and thickness.
  • Add icons, borders, or lanyard/keyring holes.
  • Preview your design instantly in 3D.
  • Download the ready-to-print STL (single-color) or 3MF (multi-color) file.

How to Make Your Own Keychain

Step 1: Enter Your Text

Think about what you want on the keychain: a name, a short phrase, or even a hashtag. Enter it into the tool’s input box.

Step 2: Customize the Design

Pick a bold font that will print well. Adjust the depth, width, and layout. Add a border for durability or choose a decorative style.

Step 3: Add the Keyring Hole

The tool lets you add a small hole or slot so your design attaches easily to a standard keyring or lanyard.

Step 4: Preview and Download

Check the 3D preview to make sure it looks the way you want. Then download the file in STL or 3MF format.

Step 5: Print It

Open the file in your slicer (PrusaSlicer, Cura, OrcaSlicer, etc.), scale as needed, and send it to your printer. PLA filament is fine for keychains.

Printing Tips

  • Size matters: Keep your keychain small enough to carry comfortably, usually under 60 mm wide. There is a US quarter in the view port so you can get a sense of scale. Too small and the text won’t print well, too large and it won’t fit in your pocket!
  • Infill: 15–20% infill is enough to make it sturdy. Increase the plate depth if you want something stronger.
  • Colors: If you want a two-color effect, you can either use a multi-material printer (3MF export) or set a filament swap in your slicer.
  • Layer height: 0.2 mm works well for a balance of speed and detail.

Other Creative Uses

Custom 3D printed keychains are versatile. You can make:

  • Event giveaways and swag.
  • School or team spirit tags.
  • Campaign and rally slogans.
  • Personalized gifts for birthdays or holidays.
  • Quick prototypes of logos or branding ideas.
