One of the LEGO® Hidden Side designers, Niek van Slagmaat, recently shared some of his design process for upcoming set 70436 Phantom Fire Truck 3000 in a series of fascinating tweets. Rather than scroll through the twittersphere trying to take in all the details, we have unrolled (and lightly edited) the threads here for you, with permission from Niek.
Niek: The new Hidden Side fire truck was my favorite Hidden Side set to design so far! With it releasing soon, I thought it would be cool to share some of my process on this set. It's important to make it VERY clear that this, as with all LEGO sets, was a team effort. I worked closely with a variety of people to make this vision work, from digital development teams to sparring partners, to quality and building instructions developers.
