❤️ Simple Heart Box – 3D Printable Valentine Gift Box

This simple heart-shaped box is a clean and versatile 3D printable design, perfect for Valentine’s Day or anytime you want to add a little love to a gift. Featuring a matching lid and base, this box prints easily and assembles with no hardware required.

The smooth walls and classic heart shape make it ideal for:

Small gifts or jewelry

Candy or treats

Desk storage or keepsakes

Decorative prints or color-swap displays

The design works great as a single-color print or can be enhanced with multi-color filament swaps for a more eye-catching look. Shown prints use gradient/multi-color filament, but standard filament looks just as good.
