MODELING SPHERES

thingiverse

Ian Gonsher designs simple design primitives called modeling spheres that can be easily configured for easy prototyping with servos. These modeling spheres allow makers and designers to begin by thinking about the kind of rotational motion they want to explore in their project, rather than starting with hardware. The DXW90 MicroServo is used as an example of this process. These elements can be combined in CAD to create more complicated forms, such as XYZ axis robotic arms and mechanical locomotion. They are designed to be "print and play," meaning the servo arms simply slide and lock into place without any additional hardware or glue. However, it's recommended to trim the servo arm as shown in the picture.
