How to Make Lego Menger Sponge

DIY, Geometry, Lego, Mathematics

An intriguing fractal shape, build from Lego. This guide is in response to the comments I’ve received from the original posting on my Lego Menger Sponge page.

Ingredients:

Lego bricks

Step 1: First Layer

You will need to underpin this layer with flat bricks, to ensure it holds itself together.

Step 2: Second Layer

Note the rotational symmetry of the pieces.

Step 3: Third Layer

Step 4: Fourth Step

This is the easiest bit, since the towers are all identical.

Step 5: The Fifth Layer

The top part of the sponge has an identical pattern to the bottom three layers. However, because it must stretch across the gaps, different pieces are often used. Note the 1×8 pieces.

Step 6: Penultimate Step

Step 7: Final Step
