Heavy Ball Spinner

When playing with this spinner, exercise caution due to its weight of 150 grams. To insert the 22mm balls or the 608 bearing in the center, first warm up the spinner slightly using a hair dryer. This allows the balls to easily take their seats and remain securely in place, assuming you printed it from PLA material. In general, the 22mm balls fit well within the spinner and hold firmly, although sometimes they do not drop out exactly as intended. To prevent this, I make grooves under the balls, ensuring they don't fall onto my foot.
