First of all, an assumption must be made - here. We create a simplified torus model. Firstly, creating a perfectly smooth body of revolution from the paper is basically impossible. Secondly, the surface of our torus will be formed from a group of rings. And between these rings is an open space. In theory, this should not be. The surface of the torus must be completely closed.
Therefore, this model claims only the title of the easiest to assemble, visual model of the torus!
10. We get a simplified version of the geometric solid - a torus.
The geometric solid dimensions are excellent - the diameter of the outer contour is 195 mm by 60 mm in height. For comparison, a sheet of A4 format and a torus made of a sheet of the same size:
The denser the paper, the more geometric the shape will be. But still, this is a very conditional construction of the torus. The biggest plus of this design is its simplicity and speed of manufacture.
By changing the stripes' width when cutting the sheet, we can get a more or less smooth design. On the left is a torus with a stripe width of 20 mm, and on the right with a strip width of 10 mm.
