I have designed a multi-thread screw that goes in a different direction when rotating. It is very smooth. Could we use it as a normal daily life tool? Now I designed this intelligent tool. This powerful hand-powered drill will rotate only in one direction no matter you push or pull the handle. I will explain the idea and concept of how to design it using Fusion 360. It is easy that even beginners can follow. The idea and concept would be used in future projects. It is a multi-thread drill made by a 3D printer first time in the world.

More design detailed information can be found in another two videos.

I like to use a 3D printer to make some new and useful things. I also like to do some detailed systematic testing. At the same time, I will share the results with you, so that you can focus on useful things that interest you. This can take your work to the next level. You can also learn a lot of new knowledge and technique.
  This is not the first attempt, but I think it is a good example of getting new ideas. I hope someone can get some new ideas from the smallest things. In addition, I hope they can share their experience with us and make the world a better place.
