I got tired of using d6's to try and track my elements in Spirit Island so I decided to make this basic tracker that would allow me to just slide the element markers along the tracks. I wanted something relatively small and compact that I could easily fit in the box.
The track is just a 4 x 6 grid so you can easily track 4 different elements with one on each line by using the cardboard element tokens from the expansions. Four different elements is sufficient for the innates for almost every spirit but there are a few that use more than four elements or need counters to go above 5. For more unique elements you can just use 2 boards or you can just track multiple elements on the same line. For tracking above 5 you can just use 2 markers of the same element and add the amounts together. I've also included the f3d file if you want to modify it to be larger instead.
I printed these at 0.15 mm resolution and used a color change after the first few layers to get the different colored backgrounds and make the numbers pop a bit more, but you can totally make this with a single color without a problem.
Note that your cardboard element markers likely have a rounded edge and a sharp edge due to how the punchboard is made and I found that having the rounded edge down on the tracker makes them slide a lot better. Having the sharp edge down tends to catch on the layer lines and not slide as well so try flipping the markers over if you find them catching a lot.
