You need to be made of stern stuff to succeed in the LEGO Iron Builder competition. Over three intense rounds, a narrowing pool of builders has to show off their skills by showcasing a different seed part. With the final round of the Iron Forge wrapped, we’re taking a look at the octet of builders in the running to win it all. Next up, Margit_MOCs, who created an impressive 13 builds featuring the seed part: engine block! The Brothers Brick is a familiar stomping ground for Margit’s creations – she even made our shortlist for 2025 Builder of the Year. And speaking of stomping, what an immaculately well-timed build this was, using the engine intake as a sturdy shoe sole. LEGO Crocs, eat your heart out.
In such a heated competition, it’s little surprise that some competition makes it into the participants’ builds, too. But neither frog nor fish seem to be able to get near this particular fly!
