Curved Racks for a Lego Cog Railway ... living in Switzerland, it's no surprise that my kids had this request. These curved racks are compatible with the standard straight racks. There are different version of racks for 4 different radii depending on the position where it's mounted between the tracks. The STL-files have a postfix A..D as indicator (A is the for smallest radius).
I was born in Zurich, Switzerland, grew up nearby. After finishing my studies in Electrical Engineering at the ETH in Zurich with a masters degree, I was working as a software developer - initially in semiconductor industries, and later many years in life science. Designing and creating innovative software, interacting with customers, and managing a small team of software developers was my big pleasure. As a hobby I aleays designed and experimented with model airplanes. When 3d-printing became commonly available, a door for a new type of creativity was opened. I had to open this door, and immediately my focus was attracted by mechanical watches and machines, and I stopped my former job. I believe, future mechanical objects will be highly customisable - not only engraving but also mechanical function. Hardware becomes Software. By sharing valuable functional designs, I'd like to demonstrate the future potential of the new technology.
