About this deal
Remembering how unusual (not the template) the past 2020 was, we can assume that 2021 is also preparing surprises for us. Of course, I really want these to be pleasant surprises. I found it easier to assemble the 2 halves, but leave a couple of the tabs loose (for example, the August & September tab), then glue the 2 halves together, finish with gluing the last 1 or 2 tabs. Cut along the outer lines, score around each pentagon shape. Gently fold along each scoreline. Step 2: Are there other polyhedra that can do this? If we want each month to be on a separate face, then we need a geometric solid with 12 faces. We can offer the reader another polyhedron. It is a Rhombic dodecahedron. He undeservedly receives much less attention than the dodecahedron.
Therefore, in addition to the mathematically accurate version of the polyhedron - rhombic dodecahedron, we will make models of non-standard shape: A model consisting of 12 rhombuses with the ratio of the diagonals of the rhombus in the proportions of the golden ratio 1 to 1.618. In case you are interested, this dodecahedron is a Platonic solid, with 12 pentagons as faces, which gives us 12 months! 🙂 Helpful tip: The fact that a year consists of 12 months is no secret to anyone. Since then, people have grouped 12 months into calendars in a variety of ways. You may have come across a polyhedron calendar before. In the overwhelming majority of cases, the dodecahedron is used as the basic geometric figure. A geometric solid consisting of 12 regular pentagons. The reason is simple - the dodecahedron has 12 faces, which means that one month can be applied to each face. For work, we need a polyhedron shape net. Let's make a polyhedron from a single shape net that can be placed on an A4 sheet.Here it is! A one-of-a-kind 3D 2022 calendar perfect for your desk, or as gifts to share with creative friends!
