My j-head is 7 mm shorter than stock (I got my machine in December) Solidoodle. It fits more snuggly in the MK4 as well.
I do want a different fan because Lawsy's fan is too low now.
This is what I'm using: http://www.tridprinting.com/Hot-Ends/

I used some High temp heat shrink and ceramic insulation. Fiber glass insulation would work also. I think the original solidoodle is just fiberglass mating covered by 125C heat shrink tubing.

With a bit of stretching, I managed to fit my Solidoodle insulating wrap around the J-Head, even with extra Kapton tape around the heater.

Where did you get it? And could you please tell me the overall height from top to bottom? I'm making my extruder compatible with both Solidoodle and J-head hot ends. I'm taking a survey of J-head heights in order to make sure my fan mount is the right height, as it's driven by the overall height of the hot end.

Thanks nlancaster!

I believe it's the same as Makergear's 1/2" rubber coated fiberglass, here (select it in the drop down list, $2.50 for 4" length).

So I upgraded to a J-head and am loving it but I do have one concern. Going to add a print cooling fan to my machine and the hotend is no insulated like the Solidoodle hot end. Anyone know what kind of tape they wrapped the ceramic insulator with? I would rather not use kapton because it is kind of ugly.
