A tower of 5 3D printed overhand knots that gradually increase in both bulk and length from top to bottom, with a man's tattooed fist next to the middle one as a size reference.
Market research time for knot aficionados! If 1 is the smallest and 5 is the largest, which of these looks most enjoyable? For reference my fist is 4" across the knuckles. Small knot (1) is ~5.75" circumference, large (5) is ~7.5" circumference.
