摘要

A first square module may have two slits (1) extending inward at 90 degrees to two opposite sides. The remaining two sides have a single centrally-placed slit at 90 degrees to the first pairs of slits. A second square module has slits extending inward from the corners along the diagonals. A third square module has a cruciform slit in the center. The slits are slightly wider than the thickness of the modules.
