Secret Storage Book - Valentine

The Secret Storage Book – Valentine Edition is created as a romantic decorative piece inspired by classic embossed book designs.

This decorative storage container is designed to resemble a classic embossed book, featuring an ornate heart motif framed by roses and filigree details. Inspired by traditional ornamental book art, the embossed relief gives the cover a refined, sculptural appearance that catches light and shadow, enhancing the decorative character of the piece.

Designed to blend naturally into a bookshelf, display, or tabletop setting, the book discreetly conceals a practical storage compartment inside while maintaining the look of a solid, decorative volume. The interior is well suited for storing small personal items, keepsakes, jewelry, notes, or other sentimental objects, and can be thoughtfully filled as a personal gift for a loved one.

The model is optimized for easy 3D printing. 

• No supports required

• Print-in-place hinges

• Low infill (10%) and only two perimeters needed

• Efficient filament usage with excellent surface detail

The internal paper-look storage box prints as a separate part and is fixed into the book cover using just a couple of drops of glue.

 PRINTING RECOMMENDATIONS:

• • Material: PLA

• • Layer height: 0.2 mm recommended (0.15 mm optional)

• • Perimeters: 2

• • Infill: ~10%

• • Supports: Not required

For best embossing quality, print the book standing upright.
A 5mm brim is recommended for bed adhesion.


HINGES:

The print-in place hinges are designed with 0.3 mm clearance and may fuse slightly.
After printing, gently flex the cover to release them.

 For extra durability:

• Add a 4 mm tall modifier cylinder on the hinges

• Set it to 4 perimeter layers (or 100% infill)

Pre-made PrusaSlicer project files are included with this modifier already applied.

Scaling: Feedback from users indicates the model scales well down to 80%, with the print-in-place hinges remaining functional. However, this has not been personally verified, and results may vary depending on printer and settings.


CUSTOM BACK TEXT:

The back cover supports custom recessed text. Add your favorite book-title directly in the slicer!

In PrusaSlicer:

• Add Text Modifier

• Set to “Cut”

• Depth: 1.2 mm

• Select the desired font and adjust size and positioning

 A ready-made text modifier is included in the .3mf files

Tip: If you plan to use the fully embossed book as a decorative desk-piece, rotate the book cover text so the text reads from top to bottom. This will ensure the text is the correct way up when the book is laying on the table.
