Spinner Designed with Tinkercad's CodeBlocks

Tinkercad's Codeblocks are the beginning of a new era in 3D design. Now artists, educators, students, and makers can quickly and easily create objects that are ready to be 3D printed. To start learning Codeblocks go to: [An Introduction to Tinkercad Codeblocks](https://medium.com/@ronm333/an-introduction-to-tinkercad-codeblocks-b896dff5f5f9).
