With the intention to make the axel shafts to the diff houses more durable to wear and tear I’ve made two new versions of it. One that are built like the input gears instead. The other version is solid and printed in one part, but to be able to put on the bearing, you have to pause mid print to put it on.
The two files can be found here

The solid one I haven’t tried printing yet, but I’ve made the diameter a little bit smaller on that part to make it easier to attach the bearing mid print.
The two part model I’ve done a few test prints of, and I’m confident the female part for the dog bones is more rigid than before, not sure if the male and female of the axle shaft it self introduces a new “weak point” though, need to make test drives to confirm or decline that.
If you decide to test these, use a 3x12mm screw for the two part model when attaching the gear in the diff-house on it, the screw will hold all three parts together and add stability to the shaft it self. If you are paranoid, add super glue in the male/female joint of the axle shaft.
I will try both of these out more thoroughly as time comes available the coming weeks, but any test and thoughts of improvements are more than welcome
