Keep your 3D Printer's heater block and nozzle clean and warm with these silicone socks.  

NOTE:  This is the 5/17 revision of the silicone sock design.  It has been modified to allow a bit more of the nozzle to be exposed.  This will give a longer life at the expense of a slightly poorer thermal insulation.  It is the right design for 90% of users, but if you know you need the higher insulation of the original sock, it is available here.

This product is compatible with the E3D cartridge style heater block on the V6.  If you have an older bead style heater block, we have an upgrade kit available here

For those who have printed with copolyesters like colorFabb XT, you know that if you don't nail the settings absolutely dead on, the nozzle can pick up little bits of material throughout the print.   The bits collect until they are big enough to be dropped off in a gooey char blob.  Doesn't usually matter much for function, but for looks it's not great.  

The silicone socks help to address that issue with a non-stick surface that covers most of the nozzle and heater block leaving only the end of the nozzle sticking out.  

The sock also provides the additional benefit of insulating your heat source.  This allows for more cooling of your print for better bridges and overhangs without the concern of accidentally cooling your nozzle and causing temperature fluctuations (or the dreaded temp fall error).  It also insulates your part from the heat generated from the heater block which will cause some improvement in quality.  

It is expected that this sock may become worn or damaged over time, and they're cheap enough that the shipping is more than the cost of one piece, so we've bundled them into multi packs.  Your future self will thank us.

Gotta have it

I've heard folks complain about them coming off but I've been using these on my hemera for a while now and never had an issue. I print a lot of Polycarbonate and it can leave the heat block a disaster. The socks definitely help to mitigate the issue. I only wish they could support higher than 300c. Either way must have in my opinion

Nice product

It does exactly what it’s supposed to do; now I can run my cooling fan at 100% without it creating thermal runaway. I used some thin titanium wire around the top of the sock on the heater block to keep it from slipping off for any reason
