Check out this amazing youtube channel of Matt Denton. He recently published his second giant lego technic built, this time it was a forklift. He 3d printed the whole kit on his 3d printers in PLA, ABS and Ninjaflex. It took 500+ hours to print them and he released designs of his scaled bricks on his https://www.thingiverse.com/mantisrobot/designs page. Check the video where he explains the process of the building this amazing object. If you have your own 3d printer
you can also build one or use his parts and build your own giant version of the kit you had as a child.
He previously built the gocart in the same scale and later made it remote controlled! here is the video showing this model.
You may not know, but Matt is an electronics and software engineer, designer and puppeteer of animatronic BB8 droids from recent Star Wars movies! Yes, he is the person who worked on original droid for the movie and later the red carpet remote controlled character you saw in many interviews on youtube.
If you are like me, fan of Star Wars lego, 3d printing and robotics, you should follow this man. He is creating some amazing projects and sharing his vast knowledge with us on his youtube channel.
