I originally cut the tank treads off the original .stl file so the body base could sit flat on the print bed. However, I still had issues with the arms breaking off when removing support material.
I wanted to cut the arms off and modify them so they could print flat on the print bed but wasn't sure how to go about doing that to an .stl. So I decided to draw it in Fusion 360!

Modeled in Fusion 360. I uploaded the original .stl file into Fusion and used it to take measurements from.
