Hi,

i search for a better insulator for my hot end and think i will make a insulator from a 5mmm PTFE plate. Is PTFE a better insulator for mounting between the aluminium cooling block and the noozle mount?

greetings

My thoughts are you should stick to the MDF insulator. It's cheap easily cut, and very good at it's job as is. I would have said there was more heat conducted by the 3mm allen screws than transfered via the MDF insulator myself.

Please send me a PM if you have suggestions, or problems with Big Blue 360.
I won't see comments in threads, as I move around to much.

I´ll try it.

I trying to build a insulator for the 2 noozle heatsink aluminium block. But it is very tricky because the walls on the holes are so thin..... 2 tries.... 2 breaking boards....

The MDF tends to break if you drill holes in it close to the edges, so I found it easier to drill the holes in an oversized piece of MDF and then cut off the excess using a junior hacksaw.
