Created for my nephews :) I used dimensions from Wikipedia: Lego, Lego minifigure

Lego units in program:

• stud - length of plate/brick with n studs
• plate - height
• brick - height
• minifigure - height

Note: There is mistake in the image above: length of plate with 1 stud is 7.8 mm hence 2 stud length is 15.6 mm
