My fellow Prusa i3 MK2S newbies . . . buy this sock!

I recently had a blob-splosion from an unattended print - similar to this http://imgur.com/a/EQDG9 - and found that one thing that would help with this is a silicone sock to cover the hot end. These can be purchased here - http://e3d-online.com/V6-Sock-Pro?search=sock.

The sock would not prevent the problem but it would have protected my printer head a bit more than it is out of the box,
