The truly periodic table of elements

The one and only truly periodic table of elements. A similar cylindric design might be seen elsewhere, however the periods are always organized as a circle of same height. The increasing Z and periodicity, however, call for a different design - the spiral, where elements with similar chemical properties (valence electrons) are still placed below each another, however each element including noble gases has both neighbours that differ by one proton. Choose your design - the project contains a few slightly different designs (full cylinder or elements only, my favourite has separation of La and Ac groups) Before printing all elements, try one or two and test how they fit on your printer. A slight increase/decrease of size might be required. The model is sized as the smaller possible that is readable when printed with 0.4 nozzle, however is usable the only for long pencils. With a smaller nozzle, print all at 75-80%.
