Chessboard to be assembled with glue. You can print all the white parts all at once (same for the black ones) or one bye one. You can even use it like a 3D puzzle game without using the assembly diagram. Perhaps your model we will not be exactly like mine but that doesn't matter if you like it ! A tip for assembly : begin with the middle of the chessboard.
You can use it with the chess set on the following link : https://cults3d.com/fr/jeu/hollow3-chess-set - It's free.
Please give me your impressions and the most important over all enjoy it !
