If you want it to spin, use a bearing 6002, it gonna fit nicelly, u can use a 3D printed one (my bearing was a printed one)How to build, if you dont want the spin, just glue the 3 pieces, if you want the spin, use a bearing 6002, glue one in the hole of the bottom part, one inside the main piece, i glued the "axis" in the middle of each bearing, but i am't sure if it was a good idea, it is up to you video: https://youtu.be/zmviSAmEnEE
