Hello this is a version of the game chess plus found here https://www.chessplus.com/
I wanted to create a version of this game because I thought the geometry was cool and would be a fun CAD adventure. I have released the .STEP files along with the 3MF files so people can download and remix as well.
The rules of the game can be found here: https://www.chessplus.com/pages/how-to-play-1
If you like this game please support the original creators by buying a set from them.
