Been working away on these pair for a while. After seeing how much it was going to cost to buy an original I decided to make my own. One is inspired by the classic kit, the other by the original scratch built model from the Rogue Trader rule book. Both were printed on my Ender 3 with no supports.
They are available on my Cults3D page if anyone is interested.
