No need to buy any bearings just download and print it. It will be ready to spin. The concept is really simple. It is like a double-sided countersink hole with a clearance of 0.6mm from the middle pin. "NO SUPPORTS" needed, but you might need to push the middle pin down when you remove it from the print bed. In order for it to spin. I hope you enjoy!
Might need to push down on the middle for it to spin.
I got into 3D printing when took Drafting and Design class at my high school. It is just fascinating to me how I can print a object of my design in my home. Instead of just looking at my design on a screen, I can now touch it and feel it on my hands. I personally consider 3D printing as a hobby like playing video games. So I made this account to share my design to the world and if you like my designs I'm happy. If you don't well give me some feedback.
