This might sound weird but isnt it easier to just glue the axle itself? I mean the Wheels arent attached to it even if the axle is fixed the wheels can still spin around

I suppose you could, assuming the wheels spin freely enough. The only downside would be if you ended up with broken wheel somehow (don't ask it does happen), you'd have to prise it off to replace the axle/wheels. But otherwise its a reasonable solution, although I like Super's idea myself
