To assemble this spinner, you will need four 608 single-row radial ball bearings. Although cheap options may suffice, investing in quality bearings like SKF will result in better performance. The brand of the bearing is more crucial than its ABEC class. Hybrid ceramic bearings can significantly extend spinning time. You can obtain these bearings from various sources: * Skateboard shops * Sport stores that specialize in inline skates * Specialized stores that sell bearings * Online retailers To prepare your bearings, it is recommended to wash them with a fine-grained lubricant like WD40 before use. This removes factory-applied vaseline and reduces friction, resulting in longer spin times of over 20 seconds. Spray the bearing a few times and spin it to ensure optimal results. However, this process may produce some noise. To minimize this issue, make sure to wash the bearings thoroughly. To print your compact bearing spinner, you will need to create one body and two bearing caps for the center bearing or eight caps to cover all of them.

After that, press in the remaining bearings, using sandpaper if necessary or heating up the holes to make them more pliable. Finally, add the caps and share your creation with others. Enjoy your spinning masterpiece!
