I improved my version of the Density Braille periodic table. This one has more readable braille and is a bit bigger to make sure its usable. I do not recommend scaling it down.
Its to big to fit my printer so i included a version splitted in 3 parts which can be glued or kept separate.
The height of the squares represent the elements density.
I havent printed the whole thing yet but there is a picture of a small piece of it (about 1/20 of the whole table). As you can see, the braille looks good. I will post pictures when i print the whole thing If anyone else does, please post the result in "made"! Thanks
Made in openscad and split in netfabb
