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
