Creality CR-10 Hotend Threaded Heatsink Block Replacement, includes block and spare PTFE (teflon) tube.
MacEwen 3D has you covered. Much sought after, this is the basic heat sink block for your CR-10, CR-10-S4, and CR-10-S5 printer. You can just screw this in place of your old one, and be on your way.
It's unfortunate that disaster can strike. A print can fail, and leave a large glob of plastic on your hotend. More often then not, this can be removed, carefully. Sometimes, you wind up with a mess, you'd rather not deal with.
Many people have managed to break off a thermal tube inside, attempting to replace it. We offer a kit for proper removal without breakage.
1) Remove hotend from your print head carriage. Loosen set screw on heatsink, near tube. Use two M6 nuts. Tighten them against each other, and use the inside nut to unscrew tube (using a wrench), or outer nut to reinstall. Remeber, "Righty tighty, Lefty Loosey".
This hotend heatsink block is the stock hotend for CR-10, CR-10-S4, and CR-10-S5 3D printers.
