Mold for heatblock silicone insulator (silicone sock)

thingiverse

I designed a custom 20mm wide heatblock out of copper for my E3D v6 and needed a silicone sock to fit it perfectly. Since the heatblock is one-of-a-kind, I had to create and mold the sock from scratch. Although this design may not suit many other heatblocks on the market, I'm sharing it in case someone finds it useful. The mold works exceptionally well even when printed with thin 0.3mm layers. To make mold release easier, apply oil, Vaseline, or soap to the mold surfaces before molding. Additionally, both halves of the mold feature holes that can be tapped for M6 threads and secured with bolts, allowing for smooth removal and replacement of the mold pieces. This solution seems to work remarkably well for creating socks (sorry, here's a link in Finnish): https://www.biltema.fi/autoilu---mp/auton-varaosat/jaahdytysjarjestelma/vesipumput/tiivistesilikoni-korkeiden-lampotilojen-2000036107
