Mars Mill

The initial vision was centered around a belt-driven bucket system, but due to size constraints, I had to pivot the design entirely. Upon adding the final details, it became apparent that the shape resembled a watermill, prompting me to dub it Mars Mill or Miller. The exterior ridges are angled at 45 degrees to maximize surface area as they rotate. Moreover, the grater situated at the bottom of these ridges enables effortless passage of regolith while keeping rocks and other unwanted debris at bay.
