Compatible with all Volcano Nozzles and all E3D HotEnds except Cyclops. This block uses the same clamped thermistor mounting configuration as the E3D-v6 Heater Block for maximum ease of use and security. The block also has a heater cartridge clamping system for maximum heat transfer, this time using two screws for clamping instead of the one in E3D-v6.

This block absolutely cannot be used with a non Volcano nozzle, plastic will go everywhere, please don't try.
