MK9 Extruder 20*20*10MM heater block
Long Lasting Insulation for 3D printer heater blocks

High temperature (up to 280°C) non-stick silicone socks for the MK9 style extruders, such as those used on the Cocoon and Flashforge 3D printers.

These socks will keep your heater block clean and free from burnt and blackened plastic. They don't just keep the block clean, but also keep heat inside the hotend and off your print.

Designed for MK9 Extruder 20*20*10MM size

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-composite materials that like to build up on nozzles.

These socks also offer a huge boost in temperature stability, particularly if you use high-airflow cooling around the nozzle to cool the print. The additional cooling combined with reduced heat radiation from the block to the print really boost the ability to print great overhangs and bridges, all while keeping the hotend temperature extremely stable.

The covers simply push onto the front of the hotend with no disassembly - they will be a tight fit when first pushed on cold. When hot the silicone will expand to the correct size to fit the hotend snugly. Unlike some other silicone covers, these have a wide hole for the nozzle to fit through, ensuring no plastic get stuck under the sock.

These socks are durable but don't last forever. Depending on what materials you print and how much abuse they get, they eventually wear away. Although even with sticky abrasive materials and a bit of abuse they should easily last 100+ print hours. With less sticky materials like ABS and gentler use you can get almost infinite life. Your mileage may vary.
