This gear fits very well in the GB03. Many thanks for this.

Had the same problem, ended up printing the top ring gear at 1.05%, which fixed it for now, but was going to do the same with the main ring gear. This is a much better solution in that it gears down, which is needed for those big 160mm tires.

Mine did this took me ages to figure out, think the diff housings got changed as it fixxed it when I printed new ones.

tahustvedt said he did eventually find a mistake in the axle. he corrected the bearing holders. he put out a new test gearbox to see if it solved the issue. there are many people with different versions of the file and things are kind of out of sync in the STL files.i left the gear up so if somebody does find the gears skipping they can try out the larger diff gear and see if the problem is solved for them.

tested the gear today did a few reverse to forward full throttle burn outs on pavement and the gears did not pop or skip at all.
YIPPY! tested 2 trucks with the same modifications nothing broke.
