You can get [item=94903] through Engineering (Pierre), although it is quite expensive and requires not only 15xLiving Steel, but also 15x[item=94113], which has a cooldown of 1 day.
It was first not tradeable to other players, but was then hotfixed together with the other new Engineering pet [item=100905] to allow for cageing. You may also now have up to 3 of this pet if you wish.
