This is a replacement silicone cover for the original E3D V6 (new version).
The original cover does not stay where it should be.
Just print all 3 parts, connect them and mold your cover.
Print everything with about 20%-25% infill. You should print the parts with 0.1mm layer height for a smoother finish.
To fill the silicone into the mold I use these needles and a normal syringe
Wait about 2 hours till the silicone is dry to clean everything.
