Optimized Handle Stem

I'm a master student in mechanical engineering at the University Paderborn in Germany. And this is my topology optimized desgin of a handle stem for racing cycles and other bikes. It has the standart measurements and is even lighter than the average stem you can buy, which is really important in this sport. It is strong enough to carry the 2300N in - 45° according to the DIN EN ISO 4210-5 Standard with a weight of 152g (0,3351 lbs) -> printed with ABS-M30. The strength is referring to FEA Simulations.
