An SU-85, 2x T-34 (Early) and a Hetzer from Bergman's great Tank Pack 2 scaled up 200%.
Hetzer and T-34s printed with Superfila Black PLA. SU-85 actually printed with test roll that was included in the Creality Ender 3 package.
Sliced in Cura 4.0 and Printed at 40mm / s at .15 resolution and .35 Line Width I printed the Hetzer first with supports everywhere in grid, which made it a little more demanding to remove. With the others, I used touching buildplate only with line support and was much easier to clean the model.
