Silicone insulation sock for Raise3D V2 hotend

Introduction This is a reusable mold designed for two-part RTV silicone casting compounds and putties. The mold creates a silicone sock which covers the heat block to insulate it. There are two separate files for both the left and right extruder hotends. I have not actually explored the thermal performance of this insulating method compared to other solutions, though, so I can't guarantee that it is better, but it sure looks cooler! This is version 1 of this, so please feel free to submit makes and feedback. I made the model in OnShape, a nice online CAD package. You can view it there and even export it if you have an OnShape account (it's free). I also uploaded Solidworks part files for it, if you want another format, let me know. These files also include parts and an assembly for the hotend itself. **Edit version 1.1:** Created an air gap between the silicone sock and the heat block. Previously, the silicone was 2mm thick, now it is 1mm thick with standoffs which create a 1mm air gap. The sock is slightly more difficult to release from the mold, but it should insulate well. Filleted the bottom of the sock.

V1.2: Improve the mold design to make extraction easier. Instructions 1. **Print the mold.** Any rigid material is fine, but print it fairly sturdy. 3 shells and 25-50% infill recommended. If you're using pourable silicone, maybe a flexible filament would work, I haven't tried it. 2. **Get some silicone.** Look for high temperature RTV silicone casting compound or putty. I have tried two types: TAP Plastics platinum cure (translucent white
