Silicone Insulation Cover for Aftermarket MK10 Heater Blocks

I needed a new heater block but could not find one with the correct thermistor configuration. A shorter version 20x16x11 (see picture) was available. So I remade the Duplicator i3 hotend silicone insulation sock to accommodate the aftermarket shorter heater block. I'm happy with the results. With the silicone insulation the heating characteristics are about the same as the OEM heater block.
