Ultimaker Hot End Thermal Isolation Sock Mold

A multipart mold that lets you cast a high-temperature silicone thermal isolation "sock" that fits over the standard ultimaker hot end. Because silicone is much less conductive that metal, the sock will considerably reduce heat transfer from the hot end to the cooling airflow, resulting in lower cooling air temperature and thus better cooling -- cooling air downstream of the hot end is approximately 10F cooler when using the sock.
