“Karakuri Small Box #8” was created based on “3D Box (K-20)”. “3D Box” was created 10 years ago. If you know the “3D Box”, maybe you are one of the veterans about Karakuri Works. 3 bars cross in a cube, and they influence each other. Of course, this works also has a space inside. The bars are unstable while making this work. It makes difficult to make. Especially, we need to pay attention to the process to make.
