Fantasy “automaton” miniatures are not particularly common, much less dwarven machinists. Following are a few recent examples I have seen. Please share any you are aware of. Thanks!
Nominally a “fantasy football team”, fortunately these multi-part miniatures aren’t carrying any footballs and could be either dwarf-shaped automatons or dwarfs in automatons/power-armor. Currency conversion and shipping outside the UK make them pricey, however.

This recently concluded Kickstarter included “Bronze Automatons of Hephaestus”: Bull, Hoplite, Hound, Minotaur and Owl.
