MechWarrior Online Hellbringer, roughly 130mm tall.
Fully articulated, and tested, all parts are error free and printer friendly. Multiple Torso and weapon options, and like the Atlas, does not require any glue for assembly. I used a scale table from Mech Warrior Online to scale the 'Mech. But if you would like to print it a little bit smaller, most of the detail and joints should still print/work at 75% ~though I have not tested this.
