SUMMARY
The discussion focuses on designing a plastic piece to fit a ball bearing with an outer diameter of 10 mm. For achieving an interference fit, it is recommended to start with a hole diameter of 9 mm and incrementally increase by 0.5 mm until a snug fit is achieved. The importance of tolerances in drilling is emphasized, as well as the ease of enlarging a hole compared to reducing its size. The use of glue is suggested as a last resort for securing the ball bearing.
