There's a replica about the Chess Set designed by Josef Hartwig during a Chess Set competition within the Bauhaus, competition he won in 1924. The cubes goes from 1cm to 1.5cm so if you need bigger or smaller one just scale. They are not the right dimensions, but they are well ratio.
I suggest to add a support because of the horses. I don't suggest any special printing settings because of the simplicity of the model, but i just printed them with a 0.8mm of top/bottom thickness, a 0.14cm shell thickness and a 10%infill, and looks good. It can be printed of course at any res you would require, with any thickness and so on, if have some quests just ask.
