Creating a smooth and efficient feed path is important for proper extrusion rates and preventing feed errors. Prevent kinks in your filament and Bowden tube with the bend restrictor. The anti-kink-spring creates smooth curves in the filament path to block snags and hard bends from occurring. This bend restrictor, made of zinc-coated music wire steel, comes in a length of 117.5mm (4.625″). Its diameter also allows for a snug fit over the common 7.75mm (.305″) Bowden tube connectors, which can be found here.
