NASA Bucket Drum Design Challenge V2

A compact scooping drum to collect lunar regolith efficiently. As it spins, the drum effortlessly gathers regolith, which flows into its scoop. The forward momentum of the mining cart guarantees that the scoop will be fully loaded. Then, as the drum continues to rotate, the regolith is directed towards the internal swirl, a channeling mechanism that concentrates the material at the center during extraction operations. When the drum reaches full capacity and is positioned for discharge, it reverses direction. The internal swirl then redirects the regolith back out of the scoop and into the processing inlet. A crucial feature on the support arm's rear is a vibrator in the shape of a square, which facilitates the movement of material along the swirl during both mining and unloading phases. This compact scooping drum has a maximum collection capacity of 16.5 liters. The design of this drum is optimized for 3D printing. Although I have depicted it as an exploded view, it should be printed as a single unit from the STL file "NASA Bucket Drum Design Challenge V2 Drum Assm.STL".
