I have seen a few very small models using something called "Modulex" pieces and have even heard that they are somehow directly related to LEGO? They don't seem to be around anymore so I was wondering what their history was?

    Not around anymore? I have a 2x5 right here! (At some time, they produced a planning board which my company still uses for operator shifts.)

    @Joubarc I meant that I didn't believe you could still buy them new. I am sure there are plenty of people who have there sets still.

Modulex bricks were produced by LEGO mainly for architects as the dimensions were more easy to scale up (they are 5mm in all directions).

You can find a full history (which I confess I didn't read) here

In time, Modulex started to focus more on signage and separated from LEGO, but it still exists nowadays.


The german Wikipedia article states that they were meant to be used by architects, etc. They are much easier to use for to-scale models, because they are 5 mm high (which results in a comfortable 1:20 scale). It would be quite hard to do that with the standard 8x9.6 mm LEGO bricks.
