Silicone Sleave for Merlin

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.

Silicone cover for Merlin Hotend

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

Making a cut

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.


Woods around the Maxon Villa

SInce i had to replace my old Lumix with a brand new Coolpix S7000 (the SD slot stopped working), i took the new camera out for a walk.
I just love it. Even a dummy user like me can make nice images with it.

Material Test: FPE Shore 40D Naturel

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.
