I designed a object that can collect particles and rocks (for example from the moon) and bring them back to the lab for examination. To use the Space Collector, you turn the handle and the rocks and particles get twisted into the box and stuck on the sticky part. The Space Collector solves this. It screws the particles in, and they stay in. Nobody uses this, in space or on earth. It would be great for scientific purposes. My project is truly unique. The ridges on the screw in the box catch the particles, and they get stuck to the inside of the box because it has removable sticky tape. The outside of the box is gold so it doesn't burn up in space. You should 3-D print the Space Collector!
