After i did the cover that you can mold around the Merlin heater block, i wanted to make a sleave that can be put over the heater.
The mold comes in three parts, just drill up the holes to 3mm and assemble the parts with M3 screws to hold them tight. It is strongly recommended to use PTFE spray or other any other separating agent. The resulting sleave has a thickness of 1mm and can be easily ripped.
I recommend printing the mold in high quality to get a smooth surface, the silicone will show every small fault of the print.
Heatblock Sleave 03
Thomas Kramm from Hackerspace FFM created some nice Silicone sleaves for the Merlin hotend. Since he uses different heating elements than I, he uses shorter ones that I currently don’t have, I created an own version of this cover.
It protects against blisters 😉 and will reduce the amount of heat lost during print. With the cover the already printed parts will not be exposed to the heat as much as without and you can be a lot less discriminate with material cooling.
You can find the STL for the mold attached
I used silicone meant for tin molds, it holds up till 450°C and i think it will last quite a while at the <300°C it is used in this case.
I used Troll Factory Type 3 silicone
3ders.org has a nice article on Michael Christou and his 3d printed planes

Michaels Print quality is second to none and i am quite proud that he uses my Merlin nozzle.
I admit it, i am a tape addict.
Somehow the appeal of tape is simply to much for me
Actually surprisingly easy and much more stable than i thought
There comes a time when some things aren’t worth the trouble any more. I have been a forums leader on CG Society for a dozen years and while it sometimes was a pita it was always rewarding enough to keep going. Not anymore.
One thing i will remember fondly are the other forum leaders on CGS. I can only watch in aw how some of them are able to do their job, despite personal attacks and everything.
Especially Leigh, hats off to her, only very few know what she really does and mean for all of CGS.

First test print with FPE Naturel – Shore 40D
The brown border at the bottom is residue from printing Lay wood before. It turned out that this residue made the FPE stick nicely to the plate, later tests with pure FPE did not work as nicely.
