I've been printing up AndiGordon/StudioDR's fantastic models from the Old Republic era available on CGtrader (https://www.cgtrader.com/studiodr) as well as Skullforge's HK assassins and wanted to add a bit more variety to the forces available; Sentinel war droids are super commonplace and seem to be used by most of the factions at the time. Anyhow, quickly edited and posed up a war droid file pulled from garry's mod resources. Prints out pretty nicely, should eventually get around to doing weapon variant too. D1 is the leader model.
