E3D v6 heat block silicone cover

My take on the E3D v6 heat block silicone cover.
Tried a couple but I didn't like the result, so I did a quick design

1.Print with supports.
2.Really low infill (10%) so it will be easier to break the inner block when the silicone has dried
3.Remove with care ;)
4.Cut the top to fit your needs
