Hand of Steel designed to be a Leman Russ equivalent. Turrets are sized to take standard Leman Russ weapons. I used Stroganoff's Shadowsword as a base and Skar84's turrets and modified the weapons to fit the tank better. Front turret and headlights taken from big0ne's LittleBlade.
Print at .1mm with supports. My Ender 3 did not need adhesion. Your mileage may vary.
Edit: Added some features, modified parts for print/fit issues.
