Anyone knows where to buy larger roll of Filament( 2kg, 3kg or heavier)? I know the pushplastic has them but they seem a little too expensive especially considering it is cost them less to produce 1 3kg vs 3 1kg filaments. I know filatruder is another option, but I am not if the extra work is worthy. Please let me know if yoi have any options. Many Thanks http://ift.tt/28OUy0V
