OpenRC Truggy Central Differential Axle Shaft

OpenRC Truggy Axle shaft - modificado by Jumawa works fine on my OpenRC Truggy front and Rear diggerential, but the Axle shaft doesn't fit for the Central Differential. So i made this Axle Shaf for the Central Differential. You need also Parte 2 and Parte 3 from the original Design. You can download the files here:
