Bearings were purchased from the local store "Bilteam". A 6201 2RS (12x32x10) bearing was used, and the grease was washed away with electronic spray; however, clean alcohol or a degreaser would also be effective. The rubber protection was removed to increase speed even more. The ball bearings are still a bit slow, so I recommend substituting them with ceramic ball bearings of the same size. I recently purchased small 608 bearings with ceramic ball bearings: Inner Diameter: 8 mm, Outer Diameter: 22 mm, Width: 7 mm. I created an insert in the old spinner for this "fidget_spinner_small_insert_small_bearing.stl" and some caps that require a screw with a 10 mm long thread; you will need to warm it up and place it in the cap with a large hole.
