3D Printer Hotend Silicone Sock Heater Block Silicone Cover for Creality Ender Series, CR Series, Anet A8, MK7/8/9 Hotend, Brown,3 Pcs

The original one was having issues. These work out well.

Fits perfectly in my ender 3 pro. Would recommend this product to any one how has ender 3 it is easy to install, works great, and keeps the heat were it need to be.

Good fit on my FT-5 R2 hotend (mk9 I think but not 100% sure.) Huge help in keeping the hotend nice and toasty, especially when blasting the part cooling fan.Would buy again. Honestly kinda surprised it's not standard on all hotends.

I needed to replace the stock insulation of the my Creality Ender 3 Pro because the material became brittle and began cracking by continuous use.I only had to remove the parts that were still adhered to the extruder hot end and put the new sock, less than 1 minute of work.I feel very happy with the result.I need to wait longer to jump to conclusion but it appears to mitigate some heat creep that was causing issues during printing.

An excellent product if you need to replace your insulation quickly. However, the sock only mostly fits the stock hotends listed, even with the stock insulation removed. is servicable and worth the price for ease of install.

I should have checked first. My Ender 3 Pro came equipped with a silicone sock just like these only black. If you don't have one, these fit perfect (I tried to make sure). One should last a lifetime of printing, but just in case, I now have 3 lifetimes of these available in a drawer.

These silicone socks are great. I have one installed on my CR-10s. I let my stock insulation get gross over time and finally switched to one of these socks. If I could do it again I would have put one of these on when the printer was new. The install is dead simple. It stays on and doesn’t move. Filament doesn’t stick to it and I have no temperature issues.I still have two extra. Guess that means I need two more printers!

I used on an ender 3. The material and quality is good but just doesn't stay on the printer. I'll be lucky my printer isn't damaged.Edit: 2/3 ended up working well so I'm going to chat the first failure up to human error on my part.

Very durable and useful in insulating the head unit. They fit snug and fine and don't impede the print.

Bought these for my geeetech i3 pro b. Every so slightly loose fitting, but if you clamp it in place using the nut that keeps the hot end secure, it fits fine. Hot end is noticeably faster to heat up & maintains temp much better. Also helped resolve some heat creep & knocking I’d been struggling with. Paid £5.40 for 3, a steal.

très bon produit très bonne qualité

The media could not be loaded. Edito mi opinión anterior (la cual dejo íntegra al final de esta edición):¡Deja restos! ojo, no comprar, está hecho de un material que no aguanta las temperaturas. No he pasado de 240 grados con él al probar algún PETG, pero es que también ha soltado ocasionalmente con impresiones a 200 para PLA.________________Título de la valoración anterior: Reemplaza (y es mejor) que en protector original de mi CR-10S Pro. Vienen 3 iguales.Por el momento muy contento con él. Se adapta mejor y me da la sensación de ser de más calidad (aislar mejor, aguantar mejor la temperatura...)Solo son sensaciones, ya que no he tenido tiempo de hacer pruebas objetivas con él.

Ich hab mir bei einem Fehldruck leider die bei meinem CR10 mitgelieferte/geklebte Heizblockdämmung abgerissen.Nicht so schlimm dachte ich mir, aber der Hitzeverlust/die Abstrahlung auf die Druckteile waren schon stark (schlechtere Qualität bei Konturen, höhere Temperaturschwankungen an der Nozzle sowie minimal erhöhter Stromverbrauch).Die Anbringung war nicht so einfach aufgrund des hinteren Stromdrahtes, der in den Heizblock führt, aber 3 Minuten Gefummel (an erkalteter Nozzle, sonst sind die Fingerabdrücke bald weg) haben eine korrekte Installation ermöglicht (siehe Bildanhang).
