Does anyone know how heavy materials are, per cm3? I'm wanting to calculate a counter weight, but don't know how large to make it. I fond something on the internet that suggested that stainless steel was 12grams/1cm3, but there was not much in the way of info, and it was not 3d printed steel. I, unfortunatly, don't have scales sensitive enough to weigh anything lighter than 10grams, so I can't weight the objects I have had printed previously. Can anyone help me?
