Silicone Sock for E3D V6 hotends or clones

After E3D released new heater block with cartridge thermistor, and silicone sock for this block, we realized that older type of V6 heater blocks are not compatible with new sock. We designed and manufactured this sock to be compatible with older V6 style heater block.

Our silicone sock design will not get loose. During testing of various prototypes we came to conclusion that "easy to install and remove" sock is not having good grip, getting loose over some period of time and can even get off
