FAQ

What can I customize?

Only the internal width and internal height. The rest of the construction is calculated automatically.

How does the lid fit?

The lid follows the same heart outline and uses a fixed printing clearance for a simple removable fit.

Is the lid top decorated?

No. The lid top is intentionally smooth so the heart shape remains the main visual feature.

What can the box be used for?

It works well for jewelry, small gifts, candy, keepsakes and decorative storage.

How should it be printed?

Print the box upright on its bottom and the lid with the open side on the build plate.
