Been 3D printing for 3 years now and am having so much fun with this community. We developed a great way to distribute cost effective starter quantities of NinjaTeks many colors of NinjaFlex. We have been adding other flexible filaments to our line of Splash Spools. 50 grams of filament on a spool with a case so its not flopping all over the place. Splash Spools store easily in a desk drawer, stacked space or even hang on a wall. Check out our website, also see 3dprintny.com . Check out my flexible filament collections and my youtube channel for interesting videos on flexible filaments.
