This is a ball bearing for filament spools. The inner diameter is 8 mm. Please prepare BB bullet separately for the ball. Please make rods of diameter 8 mm by yourself or prepare aluminum tubes.
The diameter of the hole of the spool I used in the past was 53/55/57/59/73 mm, so I included the outer frame by size for each.
The inner Frame is all common, it is divided into two. Inside the outer frame, insert the higher frame inside, Fill the BB bullets and fit the lower inner frame.
