Thingaverse is an online website used to share 3D prints and models, we used it to import models. I chose 3D fidget toys. 3D formats we used were OBJ and STI. Scale is the size of something. Union groups is a group of objects combined. A workplane is the space you work on. Here are the fidget toys.
