Sphere in 3 parts - kawai tsugite

thingiverse

People often divide a sphere into three sections that can be easily joined together using Japanese-style assembly techniques. To do this, you will need three identical parts with four elements each, which can be downloaded from the internet in .stl format. Once assembled, these three components become extremely difficult to disassemble, making them ideal for various purposes. Printing these parts is relatively simple and requires a 3D printer that can create objects of a diameter of 60 mm.
