Finding no 3D printable periodic tables on Thingiverse was a sad moment.
Which is why I made this qualitative map of reactivity of different elements of the Periodic table.
The height at a given location is the approximate reactivity of an element.
This thing was made with Tinkercad. Edit it online https://tinkercad.com/things/42T8N3DBjHq
Print it out and remember your elements!
