Big Royal Castle

Let’s do Duplo. If we talk about the most popular LEGO sets, we should not forget that even the youngest fans have their favorites. My son's favorite set from his LEGO Duplo days is the Big Royal Castle (10577) from 2014.

This microscale version has almost twice as many pieces as the original set, and comes in at a reduction scale of about 1:4. And while it seems simple, it's quite challenging to recreate the clunky touch of a Duplo set at this reduction scale.
