Secret Storage Book – Hệ Insert Modular

Take your Secret Storage Book to the next level with this modular insert system, designed to bring structure, flexibility, and organization to the hidden compartment.

This add-on set includes a range of divider layouts and removable storage boxes, allowing you to customize the interior exactly to your needs. Whether you prefer neatly separated sections or small individual containers, the system makes it easy to organize everything from jewelry and coins to screws, electronics, or other small items.

The divider inserts split the storage space into 3 up to 8 sections, creating a clean and structured layout inside the book. In addition, a set of smaller removable boxes allows you to divide the space even further - from a few larger compartments down to as many as 16 smaller ones. The different box sizes can be freely combined, giving you full flexibility to organize the interior exactly how you want.

All parts are designed to fit seamlessly inside the existing Secret Storage Book interior, maintaining the clean “paper-like” look while adding practical functionality.

The models are optimized for easy 3D printing:

• No supports required

• Fast and reliable prints

• Minimal material usage

• Clean edges for a precise fit

Whether you're organizing valuables, workshop parts, or everyday carry items, this insert system turns your Secret Storage Book into a fully customizable storage solution.
