Did you ever wanted some special designer stuff in your appartment? Own an oldtimer and spare parts aren’t available anymore?
The the incredibly cool concept of eMachineshop will help you. Download a free CAD-program. Draw and design the part yuio want (various plastic or metal materials available). Upload your drawing, the software will tell you whether its possible to manufacture your part and it will be sent to you in the desired quanitity. Way to go, mmh what could I order now… 😀

The only catch: The software runs on Windows only.
