You can use various types of wood to make this project. We recommend purchasing some hard wood with a nice, interesting texture like Rosewood, Teak, Oak,  Walnut, Chery, Ash etc.

Make all the items following the instructions given in 2D documentation and try to piece the 3D puzzle together. If some of the items do not fit to its place, rub one thin layer of wood with sandpaper, until all the items easily fit. Just be careful not to remove too much material during the sanding.
