The design is easy to print, quick to customize, and works great in single or multiple colors. Add names, short words, or symbols to create a unique keychain that’s truly personal..

You can print it in PLA, PETG, or your favorite filament. Scaling up or down is also possible depending on your preference.

 How to Customize (OpenSCAD)

This model is fully customizable using the included .scad file.
You can easily personalize the heart keychain by adjusting a few parameters at the top of the code.

You can customize:

• Text – change the word, name, or short message

• Second text line – enable or disable an optional second line

• Font & size – adjust font type and text size

• Text depth – control how deep the text is engraved

• Heart size & thickness – scale the keychain to your needs

• Keychain hole size & position – adapt for different rings or chains

All customization parameters are clearly grouped and commented, so you only need to edit values — no advanced OpenSCAD knowledge required.

 After changing the parameters, and rendering the model, export the stl, slice it and print it.

For multicolor printing export all STL files needed (body + text or body + symbol or body + text + symbol), and then load them all as a single object into the slicer
