I modeled a Huarong Dao Set with the original Chinese characters engraved.
Huarong Dao is the chinese name for Klotski: https://en.wikipedia.org/wiki/Klotski. This is a traditional, well-known solitaire game, which turns out quite challenging. Follow the link and you'll get all the information regarding how it is played and what the goal is.
I do not own any set, so I worked with the photograph available in: https://en.wikipedia.org/wiki/Klotski#/media/File:HuaRongDao.jpg
I tried a few automated vectorizations, but I was not completely satisfied with the results, so in the end I hand-made them (with some effort)!
There are 8 models. One is the board, the other seven are the different pieces involved. You need to print 4 copies of the small squared pieces, just one copy for the rest.
If we take the side of the small piece to be 1 unit, all pieces have 0.02 in each side. That is, they are designed so that there is a small gap that helps sliding them along each other.
I know nothing about chinese writing. Those in the pieces were made using the font here: http://www.myfontfree.com/dflikaishu1b-myfontfreecom71f129323.htm. I hope they are correctly made and used.
Some Blender renders are included.
