The Optical House: Making the Path of Light Visible

Welcome to the Optical House - an interactive 3D model designed to bring the fascinating laws of geometric optics to life! By cleverly positioning internal mirrors, the physical path that light travels inside the house is extended. This creates an amazing optical illusion, making the interior space appear vastly larger and deeper than it actually is.

It serves as a great example of visualizing physics by bringing the invisible path of light rays to life.

Educational Features Included:

Foldable Light Path: An auxiliary geometric guide that folds and fits perfectly inside the house, physically demonstrating the exact zig-zag path of the bouncing light rays.

Printing Tip: I highly recommend printing this part in TPU to ensure flexible hinges. While PETG also works, it is much less fatigue-resistant. If you use PETG, make sure not to bend the hinges in the opposite direction to prevent them from snapping.

Three Scaling Cylinders: Multi-sized cylinders that you can place inside the model to experiment with depth perception and play with the scale and proportions of the reflected objects.

Print & Assembly Details:

3D Printing: Highly print-friendly design. It is very easy to slice and requires only minimal supports. (Print profile include all settings)

Assembly: Incredibly simple, quick, and hassle-free. Just take care about walls inside during mirrors assembly

Required Mirrors: Designed for mirrors measuring 75 mm x 75 mm x 1 mm (approx. 2.95" x 2.95" x 0.04") (purchase link: https://amzn.eu/d/0eWTn6kC).
