This project looks simple until you realize how much engineering went into it.

The original assets were never meant to be physical, so they had to completely re-engineer isometric tricks and floating geometry for 3D printing. Releasing the files instead of an expensive collector's edition is a classic Factorio move, and I personally love it. Now the community can remix these and build some awesome stuff that the original devs could never imagine. Awesome stuff!
