As the title suggests, I'm looking for suggestions on producers of small, suitably Imperial themed, bits for a set of industrial themed bases. I'm thinking along the lines of all the little greebles that come with the Sector Imperialis/Mechanicus kits (I'm ruling them out as I have no use for the larger terrain sections at the moment and I dislike their overly cluttered designs). Essentially small bits like fans, vents, lamps and consoles that will comfortably fit on a 32mm base. I've tried the companies listed below already, so I'm canvassing for any alternatives (I'm open to any 3D print links too if there's a particularly good designer someone has come across):
Kromlech
Zinge Industries
Anvil Industries
Puppetswar
Zealot Miniatures
Victoria Miniatures
Scibor
Any help would be appreciated
