About this 3D model

If you are a dog lovers, like me, this spinner is for you! ;-) Designed with bones profile in mind, It uses a single bearing, therefore is very inexpensive; nevertheless the weight is well distributed, and the time of spinning lasts long. The bearing used are standard skateboard 608, 22mm in diameter, and nuts are 8MA, 13mm hexagon; no need for glue, normally. **The caps used for the bearing in the simple spinner without covers are not my design; I have used this one: https://www.thingiverse.com/thing:1848330 For the cover version, a slighty modified version it's enclosed. Enjoy!
