Here you can see a simple heart with keychain or necklace ring. Source file to modify in OpenSCAD included.
You can adjust the height of the heart when you modify the line “linear_extrude(height = 10)”.
Feel free to modify it and do your own versions. Even with names or symbols inside is possible.
In my models, I always try to achieve a fast print time and an easy printing experience.
