Selfmade 3D world map for your home decoration. The original size lead to a world map with 40x26 cm. If you have a printer with 220x220 mm bed you can use a scale factor of 150% in X/Y and the world map will reach the size of 60x40 cm. You can print the 7 parts in 6 build jobs without support structure. At the end you have to glue the parts together like in the picture.
