These are silicone molds for a heavy duty improved hotend insulation, i'll post pics as soon as the silicone hardens, also use an acupuncture needle to stir the bubbles out of the mold. http://www.ebay.co.uk/itm/262727692277?_trksid=p2057872.m2749.l2649&var=561665046065&ssPageName=STRK%3AMEBIDX%3AIT Enjoy ;)
