This little guy I made because I could nowhere find any cufflinks about technical stuff of airplanes except some that where whole airplanes. It is supposed to look like a GE90's fan. Obviously a real GE90 jet engine has much thinner fan blades and also a spiral on the so called spinner cone that is not actually recessed or elevated but only painted on it. Also The real fanblades have no marks in them. They do have a titanium leading edge though, whereas the rest is made from carbon and other stuff. The mark in my cufflink model does however give it a real charakteristic look I find.
Hopefully someone shares my enthusiams and interesd in aerospace engineering and would like to have a pair of these. Thank's for coming to whoever reads this.
