I've been a fan of Legos for years, and when I saw others printing large scaled Lego models, I figured I would have a go at it. Lego just came out with new City Space themed sets. I saw the robot in this set - https://www.lego.com/en-us/themes/city/products/rocket-assembly-and-transport-v29-60229 - and thought it would be perfect as a first attempt.
The files are at 100% (no scaling) so you can scale your's to whatever size you may want. I printed my at 400%. The face was laser printed on sticker material. The file for this is scaled to 400% so you will need to scale that down if needed.
I make no claim to the accuracy of any of the pieces. Fitting will be based on the accuracy of your printer. Good luck and enjoy!!

I used supports on all of the prints of .1mm. Make sure to use dense supports to minimize drooping and maintain part accuracy.
