i spent far too long calculating this so i must share this stupidly i have created.
a bella bot (aka kerffus) is 1290mm tall, and 556mm wide, if we assume the amount of boobage is a cube of 500mm x 400mm x 500mm (on the lower end of this measurement) and we assume it is made of silicone, the mass of the behonkers on this bitch is 233 KG, i was going to calculate if this would topple over because of that amount of mass, but i think this speaks for itself.
