LEGO Jet Engine
The LEGO company has a great web site for fans to submit their ideas. One submission caught our eye for its obvious excellence in LEGO engineering. On January 24 Dan Cody submitted his design plan and has already gathered over 3,000 supporters. If you achieve 10,000 supporters the LEGO company may review your idea and make it an actual LEGO set.
One look at the internal structure and you will see the detailed design Dan put into this build.
This build isn't for everyone, but it certainly would look good in an office and can be used to teach jet engine construction.
Great job, Dan! See Dan's work at https://ideas.lego.com/projects/f18a11c6-f704-4827-b06a-fba84e5818df
