Remix of Crazydog's Hotend Mold. - Shout-out to him!
This remix is thinner (3mm vs 4mm silicone) and with bevels so it has better compatibility with Hotend cooling ducts. This one ist completely compatible with Thorped's Fan Duct which im using.
While the Extruder is only slightly modified from Crazydog's version, the Mold is completely new.
Compatible with Wanhao Duplicator i3 V2.1 with the Heaterblock dimensions: 19.5 x 19.5 x 13.5 mm
And probably re-brands of the Duplicator i3 V2.1 as well.
Update!
New bigger version (Name of the new files is "_big"):
Old version had 2.5mm thick silicone walls, the new has 4.5mm on each side. Top and bottom is still 2.5mm to keep clearance.
I uploaded new pictures as well, as you can see it is still kompatible with Thorped's Fan Duct.
With the Hotend to 250°C the surface of the silicone gets 125°C hot with the new one, with the old silicone sock I got >150°C!

Post-Printing
What you need:
- A file to make the parts fit into each other tightly
- Heat resistant silicone (I used Trollfactory 2 component silicone for tin casting - resistant up to 450°C)
- Small scissors for touch ups of the silicone
- File of the irregularities of the smaller square hole and the cube on the bottom part so it fits tightly in the case.
- File of the outsides of the four beams on the hotend so that if fit in the mold.
- Mix you silicone together (you'll need about 14-16 gram) in an plastic cup or similar. (don't use that for food afterwards!!)
- Pur in the Silicone to about 2/3 or 3/4 of the Mold.
- Put in the Hotend slowly, press it down and align it good. The silicone should be covering it and about exactly as high as the case.
- If the friction doesn't hold everything together, use tape.
- Wait until silicone is hardened out.
- Take of the bottom of the mold, push out the silicone/Hotend from the mold case, get the Extruder out.
- Do little touch ups with small scissors, the holes are probably still covered by a thin layer of the Silicone
- Mount it on the printers Hotend. (The Hotend must be free of the previous insulation!)
