Lego superfans Jarren Harkema and Calvin Hartley studied Star Wars: Episode IV religiously, and spent hundreds of hours planning, designing and creating a Lego Technic replica of the Sandcrawler. It’s an impressive 3-foot long, 28-pound, 10,000-brick behemoth.

Harkema and Hartley met at a Lego robotics club and have been friends ever since. They spent over 500 hours creating the mammoth vehicle, and recently revealed it at Chicago’s Brickworld Lego convention. It was nominated for “Best Mechanical Creation.”

The idea for the Sandcrawler was born in Hartley’s basement “that is “literally devoted to Lego” with tables, plastic tubs and an entire wall with drawers full of building elements. They chose the Sandcrawler because it provided a lot of interesting challenges when it came to the mechanics. The original building team started out with five, but gradually “whittled itself down to just the two of them,” said Harkema. – Michigan Live

This isn’t the first massive Lego Sandcrawler (and you can always buy this 3,296-piece official set), but it’s an amazing technic build nonetheless. Here it is in action:
