3D printed objects in mechanical education

Title: 3D printed objects in mechanical education. Watch on youtube:

On MATE University in Budapest I am teaching Basics of Mechanical Engineering. To my students (future food engineers) this is not a primary course and I noticed that for some of them it is hard to understand some basic mechanical elements. I know that if they can see the part in real life and hold it with their hands, they will much easier understand and remember how they work.
