How to make a name keychain
- Type the name and choose a font. Bold fonts give the strongest letters.
- Choose the shape: an outline that follows the name (counters filled, one smooth blob – the popular two-colour look), or a classic rounded plate, with the ring on either side. Add a ♥ or ★ over the i, or a contrast outline layer for a third colour.
- Set the length. 50–80 mm suits most key rings; the letters scale to fit.
- Download a single STL, or the 2-colour ZIP for AMS / MMU printers.
Printing it in two colours
| Printer | What to do |
|---|---|
| Single-colour | Add a filament change / pause at the layer shown under the preview (the base thickness, 2.4 mm by default). |
| AMS, MMU or tool-changer | Download the 2-colour ZIP, load both STLs as one object and assign a filament to each part. |
Recommended print settings
| Setting | Value |
|---|---|
| Material | PLA or PETG |
| Layer height | 0.2 mm (0.12 mm for small text) |
| Walls | 3 |
| Infill | 20–100% (small parts are nearly solid anyway) |

Frequently asked questions
How do I print a two-colour keychain on a single-colour printer?
Add a filament change (pause) in your slicer at the layer shown under the preview – that is where the letters start. Print the base in one colour, swap filament, and the raised letters come out in the second colour.
What is the 2-colour ZIP?
It contains the base and the letters as two separate STL files that line up exactly. Load both into Bambu Studio, OrcaSlicer or PrusaSlicer as one object with two parts and assign a filament to each – ideal for AMS or MMU printers On Bambu Studio or OrcaSlicer it is even simpler: download the Colour 3MF – one file in which every colour is already a part set to its own filament (1, 2, 3…), so it is ready to print on an AMS.
What size should a keychain be?
50–80 mm long suits most key rings and bag tags. Keep letters at least 6 mm tall so the text prints cleanly with a 0.4 mm nozzle.
Is it free to use?
Yes. Make and download as many keychains as you like, with no account. Everything runs in your browser.
Which font works best?
Bold fonts (Bungee, Titan One, Fredoka, Bold rounded) print most reliably. For names, the Script group (Pacifico, Lobster, Satisfy, Dancing Script…) has joined letters so the whole name prints as one piece; thinner scripts are automatically thickened a little so every stroke stays printable. Scripts look best on a tag of 60 mm or longer.
