Brass & Aluminium Pen Holder
Designed a pen holder made of brass and aluminium and produced it on a CNC machine — together with a matching pen of my own design.
I'm a 19-year-old mechanical engineering student who loves turning ideas into real, working parts — from the first sketch to CAD to something you can actually hold in your hands.
I'm Karen Albertini, and I'm studying Mechanical Engineering at the DHBW. The dual study program means I switch between lectures at university and hands-on work at my partner company, Otto Egelhof, so I get to learn the theory and see it in action.
I'm half French, half Japanese, and I speak four languages: French, Japanese, German and English.
My path here started with my hands: making jewellery, sewing, always building something. Engineering felt like the natural next step.
What I love most about engineering is that moment when something on a screen becomes real. I enjoy design, problem solving and figuring out how things work — and I'm always happy to take something apart (and put it back together).
Outside of engineering you'll often find me at my sewing machine — making clothes from scratch or upcycling old ones into something new.

A creative side of me: sewing clothes from scratch and giving old pieces a new life. Turning a flat pattern into a 3D piece that fits takes the same precision, material sense and patience as engineering.
In my practical phases at Otto Egelhof GmbH & Co. KG I work on valves: supporting their development and optimisation and running tests in a real industrial engineering team.
DHBW — alternating theory phases at university with practical phases at Otto Egelhof, where I work on the development, optimisation and testing of valves.
Finished school with two diplomas, the French Baccalauréat and the German Abitur — and a clear idea that I wanted to build things.
Long before engineering, my hands were always busy. I designed and made my own jewellery, kept coming up with new ideas and even tried selling my pieces. Later I started sewing clothes from scratch and upcycling old ones. Wanting to understand how things are made — and to make them better — is what led me to engineering.
Whether it's a project or just a chat about engineering — my inbox is always open.
