When you change the nozzle, do you end up having to take the sock off the heat block to get a wrench on there anyway? Is there something with your setup where you can’t slip the sock off?

You only need a wrench on the heat block if the hotend is not structurally sound (using the heatbreak structurally). Otherwise you just use a socket or open end wrench on the nozzle.

What nozzle system do you use? The official procedure with the E3D nozzles like you pictured the socks for, is to hold the heat block with a wrench or pliers, so you aren’t torquing the heat break or the aluminum cold end’s delicate threads: https://e3d-online.dozuki.com/Guide/Changing+Nozzles/45

If you have a concept that could improve on existing designs, you could potentially cast your own, by 3D printing a mold and using a high temp RTV silicone like this stuff for engine gaskets: https://www.permatex.com/products/gasketing/gasket-makers/permatex-high-temp-red-rtv-silicone-gasket/?locale=en_us

@ChinchillaWafers: I'm not using E3D. I just showed those as an example of a similar product. I'm using MK8 style hotend, but whatever I use in the future will also have proper structural bolting of the heat block to the heat sink and toolhead body, not relying on the heatbreak as a structural component like E3D and many others do.

(Asked by: username_0 on 2021-06-25)

Is there a readily available silicone sock that goes *just* over the nozzle, to supplement an existing sock around the heat block body? I've seen a product for the E3D V6 that goes around the entire assembly and only exposes the tip of the nozzle:

![E3D V6 "SOCK PRO"](https://i.sstatic.net/Ty92Z.jpg)

but it's for a specific block shape and doesn't facilitate easy nozzle change. What I'd like is a piece that fits over just the nozzle, with a friction fit to the existing block sock. The benefits I'm looking to get from this are:

* reduced radiative heat transfer from the nozzle to the already-printed material
* more consistent/stable temperature in the nozzle under air flow from cooling fans
* eliminating sticking of PETG to the nozzle body
