Make this Valentine’s Day extra special with a custom heart-shaped box! This generator lets you create a perfectly sized box with your own text engraved on the lid. Building on my original box generator, this Valentine’s edition adds the option to personalize it with your own heartfelt message for a unique and meaningful touch.

Key Features:
- Custom Text: Add up to two lines of text (Names, Dates, "I Love You", etc.).
- Flush Inlay: The text is designed to be 0.4mm deep (2 layers) by default, creating a smooth, flush surface when printed face-down.
- Perfect Fit: Adjustable tolerance settings ensure the lid fits the box perfectly, regardless of your printer's accuracy.
- Fully Parametric: Resize the heart size, box height, and wall thickness to suit your needs—from a tiny ring box to a large gift container.

How to Customize:
Click the "Customize" button to open the Makerworld Customizer, modify the text, size, and colors, then download.
