The file 'Mutual Containing Boxes 3D Printer Model' is (scad,stl) file type, size is 5.7KB.
If the thickness (t
) of boxes and height (h
) of the inner box are known, the width (w
), length (l
) of the inner box and the width (W
), height (H
) , length (L
) of the outer box have the following relationship:
H = h + t
w = H + 2t
W = w + 2t
l = W + 2t
L = l + 2t
A bigger h
and a smaller t
will make boxes more like a cube so more magical when playing them. Using a smaller h
and a bigger t
is helpful for understanding why they can contain each other.
The original idea is from 黃敏晃, a professor of mathematics retired from National Taiwan University. I just make a customizable model as an easy teaching aid.
