Wanhao D6/MakerSelect Ultimate Silicone Boot for heat block

thingiverse

This is a simple cutting apart of a very nice design for a silicon high temperature 'boot' to shield the 3D printer heat block from excessive fan cooling which can lead to failed prints. A picture has been posted of a way to use just the central piece and manually make the required boot and avoid having to buy and make the custom goop as seen in the thing I mention below. So my boot looks rather rough but works very well. Have added two pictures with the more finished looking fully molded boot. I used mold max 60 with great results using the PLA prints shown here. I coated the mold with very thin layer of vasoline (applied then wipe off with q-tip). They came out nice and I used the stock 100 part A to 3 part B but only made 50 grams which was plenty. Another option that works but does not look as nice and is thicker is you can lightly coat the central piece that looks like the heat block with Vaseline for a release agent to remove the dried silicone then apply 1st coat and let dry for 2 hours. Next apply 2nd coat to fill in any gaps or very thin parts and also to smooth out the surface with a Popsicle stick or other flat tool. Please see thing 1817230 for official credit for this part. This is just a split to the 3 pieces.
