Design refinement (final dimensions and proportions)

After several weeks of testing and drafting, I have settled with a set of dimensions for my designs. These numbers are took into consideration the mudularity factors. The angles are made fixed to allow all modules to be matched nicely when placed sides by side. The height and width dimensions are set specially for kids 5years old and below.
*although overweight or bigger kids of that age are not considered in this study.

There will be a total of 3 or maybe 4 modules in this design set.
