Hello all, I’ve been burning through a lot of filament due to the recent craze in fidget spinners as well as due to a lot of personal projects. I was wondering if there was anyone out there who has one of those filament extruders, and if so on average how much do you save as opposed to just buying filament from a site such as Amazon. Also, how practical is it? http://ift.tt/2rT1YZv
