A brief story:
AC-35 is a battery for small workers with a great power. It was designed to have not just power but portable, to go not just to Mars, but designed to explore or conquer new planets. Some people say five of then can energize a small town. This one is old, and almost dead. But it keep working…
I made this model while I was following the Blender Bros course about hardsurface and learning Hops and BoxCutter. Everything started as a test. But I liked the shape and I started to put some details with hops and boxcutter.
I hope you liked my little story 
and my battery!
