A short introduction to Blender in order to design 3D printed objects
Blender is a Free software with which you can do many things, from animations to video editing to 3D modeling. You can download it at https://www.blender.org/.
It is very easy to get lost in Blender as it can do so many things.
In this unit we are going to see some very simple but useful actions in order to start playing with Blender. We will not create any objects but we will use the existing cube provided by Blender and we will use it in order to print it out to a 3D printing
What you will need at the end is a .stl file which stands for Stereolithography.
