A replacement gear set for a children’s bicycle bell , designed to replace the small plastic gear mechanism that can wear out or break over time. The model uses a 20-tooth large gear and 8-tooth small gear with a smooth, rounded “sword/blade” style tooth profile. The two gears are modeled as a single stacked assembly for easy printing and replacement. Dimensions Large gear: 20 teeth Large gear diameter: 19.4 mm Large gear thickness: 2.5 mm Small gear: 8 teeth Small gear diameter: 8.8 mm Small gear thickness: 3.5 mm Center hole: 3.18 mm Please measure your original bell mechanism before printing. Bicycle bell mechanisms vary, so this model is not intended to be a universal replacement. Because this is a small mechanical part, dimensional accuracy is more important than maximizing print speed. If the center hole is a critical fit, consider printing a small test first.
