Silicone Sock mold for new e3dv6 Volcano

This was based on: http://www.thingiverse.com/thing:1845407, I want to give credit to the inspiration design. This is a rework of a mold to create a silicone sock for a new 3D cartridge style volcano hotend. I used 2 methods to make the actual socks. I used 2 part high temperature silicone -- Mold Max 60 for prototypes. It cures fairly quickly -- I let it cure for 24 hours and was able to test molds quickly enough. I suggest make several molds as air pockets tend to get trapped and generally 1/3 to 1/2 of the molds I made were failures. The 2nd, more permanent set I made were from regular 1 part RTV high temp silicone. This takes much longer to cure -- I gave it 5 days. Again, half of the molds failed because of air pockets but the other were perfect. I basically poured some mixture into the assembled mold, then insert the insert piece and let it force out the excess. Then use a syringe to backfill from the other side. It's very hard to fill the mold entirely with a syringe, I found it to be impossible for the silicone I was using.
