Mini 1:1 Right-Angle Gearbox Kit for 4 mm or 5 mm Shafts

✅ Change the drive direction. The bevel gears take the drive around a right angle, where the shafts cannot line up.

✅ Keep the ratio unchanged. The transmission is geared one to one, so the input and output turn at the same rate.

✅ Match your shaft sizes. Choose 4 to 4 mm, 5 to 5 mm, or a mixed 5 to 4 mm pair.
