Made modified version from CNCKitchen's silicone sock mold, wanted to cover more of the nozzle like E3D "pro sock" + cover that heater cartridge screw.
You'll need 4x 3x40mm bolts + nuts for assembly.
Used same Troll Factory Typ3 silicone as original.
Watch CNCKitchen's video for tips & tricks to mold.
STL & STEP files provided.
Print in 0.1mm or 0.2mm layer height
