Upgrade your E3D V6 Hot End with the E3D Silicone Sock. This handy pack of 3 V6 socks will keep your 3D printer running smoother for longer. Silicone socks offer small but significant changes to make 3D printing with E3D HotEnds even easier, cleaner, and faster. They cling tightly to the heater block and last longer than ever before! Made of a heat-resistant, non-stick silicone material our socks will repel build-up of molten plastic. This really helps with sticky materials like Co-Polyesters and filled materials that like to build up on nozzles. Offers a huge boost in temperature stability, particularly if you use high airflow cooling around the nozzle to cool the print.
