I have v2 extruder 3mm and I have issues with printing ABS when fans hits in. Temperature drops just bellow the threshold and firmware aborts.
I was looking for silicone sock, but with no luck. So I am wondering if there is a way of replacing just a heater block for something that is near drop-in replacement which has option for a sock ?
Any V6 compatible hot end can go in place of the Hexagon. The “throat” gap of the Hexagon (4.50mm) is slightly smaller than that of the V6 (6.0mm), so a V6 is going to be loose in the aluminum plate. To make it snug, you can print a spacer out of ABS or PETG. With it being the cold end, after the fins, and connected to the big heatsink of the aluminum plate, it will be fine that it’s not metal. Optimally, it would be 1mm thick against the top of the throat and .5mm against the bottom of the throat to put the opening at the exact same height of the Hexagon.

The whole thing is likely to be longer than the hexagon, so ensure your Z endstops are set appropriately.
Thanks. E3D hotend ordered. I will just print the spacer as you said. Should be ok.
I have BL Touch, so I will need to print the spacer for the probe as well.
I stumbled across this image on a page I cannot recall - at some point in time these existed. Actual silicone socks for hexagon hot ends.
This looks like custom made. I am not sure, but to me it looks like layer lines on the side. Someone probably printed mould and used high temperature silicone to cast the sock.
Something like: https://www.youtube.com/watch?v=O5UiXky85hA
There is a model on thingiverse
It was a real product.
Look in third image.
I’d have believed they just made some really good ones, but you can see the hexagon logo on the front in that picture:
ENHANCE!
I did some using the mold myself, but after doing better ducts for part cooling haven’t seen a need for the sock.
I redesigned the fan shroud for E3D hotend if anyone needs. It fits backplate of Moarstruder.
It looks like it might be too tight against the fins, remember that axial fans don’t work against obstructions, so you would get much more airflow with about 3mm gap. This is the reason for the “dual extruder v3” heat creep fix that spaced the fan away from the heatsink:
Yes, it is almost touching the fins. My reasoning was to minimize airflow downwards so it doesnt create draft on the print (if parts fan is off). Might play with the spacers if I see any issue… its bit different then picture you shared, as there it creates backpressure from the plate below the fins. In my case fins are opened, only middle cilinder would stop the flow,
You can leave the bottom close to the fins, but open up around the top.
