Here is our selection of the best mechanical STL files, all of these beautiful creations are from the Cults 3D file library and are easily 3D printable. All you have to do is print the different STL parts of these projects, assemble them and enjoy the super satisfying result of a perfectly working mechanism !

For a long time, 3D printing was limited to very simple objects, but 3D designers are increasingly proposing complex creations - which certainly require some work after printing - but which allow for the realization of very successful projects. These mechanisms are most often presented in the form of simple gears, but in some cases, the addition of multiple gears and especially their particular shape can generate real small dioramas.

3D printing is obviously an incredible technical achievement, but projects with gears add an extra layer: assembly. So you will really have your hands in the project and will have a real feeling of satisfaction once the assembly is finished. Then, just turn on the mechanism and enjoy the rendering!
