Model of the Week: Giant LEGO Bulldozer [Track Forward, Boom Down!]

Ever since we saw Matt Denton’s LEGO Technic Go-kart, we’ve been keeping an eye on his YouTube channel for what’s next. He’s gone through phases of small hexapods, large hexapods, animatronics, Arduino controlled hydraulics and, most recently, massive 3D printed LEGO kits.

After completing two other giant LEGO builds, we were pretty sure it was going to be… ANOTHER GIANT LEGO BUILD. When we saw it was the 1979 LEGO Bulldozer (Kit 856)… well, we ran outside, started making construction sounds and crashing into random people, spreading THE JOY.

Yeah, we see what a cool uncle you are Mr. Matt.

This build is 372 pieces (!) printed on a Lulzbot TAZ 5, TAZ 6, and Mini 3D printer. He used premium PLA filament from 3DFilaPrint as well as 1.75mm Grey and Black Polylite at a resolution 0f 0.3-0.4mm with no rafts or supports (varying infills). The total cost came in at ~$683 USD (£514) with a build time of ~650 hours.

Each set of bricks is organized by color into zip files and he provides the 3D model (.scad) files as well, He also breaks down both the time, cost, part number and material quantity for each piece in a very handy parts list.

You can snag the model files and all the details on the Thingiverse project page. (Bonus! Check out his other giant LEGO builds on his YouTube channel and find all the files on Thingiverse!)
