Holobox 2 – Holographic Illusions Within Everyone’s Reach

Holobox 2 is a 3D-printable box designed to transform your smartphone into a window into imaginative worlds. With a simple yet ingenious system of internal reflections, it creates the optical illusion of holographic images seemingly suspended in mid-air, visible through the front panel. Whether it’s rotating planets in deep space, fish swimming in a virtual aquarium, or fireworks igniting a dark sky, the effect is instant and breathtaking.

Easy Printing, Guaranteed Results

The model is optimized for FDM printing with PLA, preferably in black for better contrast. No supports, brim, or raft are needed.
Recommended settings:
• Nozzle: 0.4 mm
• Layer height: 0.2 mm
• Infill: 15%
• Final dimensions: 116 x 185 x 99 mm

The free file includes the “Holobox 2” text on the front. If you wish to print the text in a different colour from the main body, simply split the model in your slicer before printing.

For supporters, a commercial version is available which does not include the front text and may be used for professional purposes.

Key Improvements Over the Original

Holobox 2 is the evolution of my first Holobox. It features a wider front window, an internal guide for easy smartphone placement, and a drawer-style adapter for devices with screens shorter than 15 centimetres.
Upon request, I can provide custom drawer adapters for other smartphone models, provided they fit within the maximum dimensions of Holobox 2.
Additionally, the model includes an optional rear panel for those who prefer a fully enclosed design.

What You’ll Need to Complete Your Setup

To fully enjoy the holographic effect, you will need a transparent panel measuring 13x18 cm with a thickness of about 1 mm (similar to the acrylic panels used in standard photo frames). Simply slide the panel into the dedicated internal guides of the Holobox.

How Holobox 2 Works

Place your smartphone with the display facing down in the top frame. Play a fullscreen video with sharp contrasts—such as scenes of swimming fish on a dark background, stars, planets, or fireworks—and watch the magic as the image is reflected onto the transparent panel, creating the illusion of a hologram.
