Embodiment Construction

[0023] The hollow three-dimensional shape is formed by plugging 20 identical components such as component A, component B, component C, component D, and component E. Each component is composed of two congruent equilateral triangular parts, that is, an inner part and an outer part. The dotted line is used to indicate the positive fold line of the front half fold, and the solid line plus a circle is used to represent the reverse fold line of the reverse face fold;

[0024] The method of making the inner part: take equilateral triangle paper, draw a connection line between each corner and the midpoint of its opposite side, and the three connection lines intersect at the midpoint of the equilateral triangle paper, that is, the first intersection point; the first intersection point to The part of the line connecting the corner of the paper is the inverse fold line of the paper corner; the part of the line connecting the first intersection point to the edge of the paper is the positiv...

Abstract

The invention provides a method for making a hollow solid figure, and relates to a method for making paper utensils. The hollow solid figure is formed by connecting 20 identical components inn an inserted mode, and each component is formed by combining an inner part and an outer part; each outer part and the corresponding inner part are combined to form the corresponding component which is provided with an interlayer, and each component is in a new equilateral triangle shape; each component comprises three inserted portions and three inserting portions; the components A, B, C, D and E are inserted circularly to form a regular-pentagon-shaped body; other components are inserted in the same method, five inserted portions and five inserting portions are combined to form one regular-pentagon-shaped body, and a round cube with 12 regular-pentagon-shaped bodies is formed and is the hollow solid figure. By means of the method, design is novel and ingenious, the hollow solid figure is easy to make, the components are easy to combine, the hollow solid figure is formed in an inserted mode uncomplicatedly, and the appearance is peculiar and beautiful.

Description

technical field [0001] The invention relates to a method for making a three-dimensional shape, in particular to a method for making a three-dimensional shape made of paper. Background technique [0002] At present, known three-dimensional shapes are rarely hollowed out, and the firmness of the hollowed-out three-dimensional shapes is often not high enough, and the manufacture of the hollowed-out three-dimensional shapes is comparatively complicated. Contents of the invention [0003] In order to overcome the disadvantages that the existing three-dimensional shapes are rarely hollowed out, the firmness of the hollowed out three-dimensional shapes is often not high enough, and the production of the hollowed out three-dimensional shapes is relatively complicated, the invention provides a method for manufacturing the hollowed out three-dimensional shapes. [0004] The technical solution adopted by the present invention to solve its technical problems is: the hollowed-out three...
