In this chapter, we came across gears from an add-on in Blender, parts designed to move freely within constraints, and a print inserted to create motion. This has been an interesting project. Also, hopefully its application to useful devices should be obvious.
While Blender's gear add-on may not be the best, the gears it produces can be perfectly serviceable. There are other gears that can be downloaded from Thingiverse, if something of a more technical sort is desired, which can then be imported into Blender, and incorporated into any project.
The creation of mechanical interactions is never easy, but it can be one of the best uses for 3D printers. Blender has proven to be adequate at this task.
In the next chapter, new modeling tools will be introduced and explored that will open up new modeling possibilities. Skinning a mesh and sculpting tools will be combined to make a detailed, organic model.
