Ender 3D Printer Parts Silicone Socks/Aluminum Heater Block/Stainless Steel Throat for MK7 MK8 Extruder Kits Ender 3/Ender 3 Pro/Creality CR-10 /CR10S /S4 /S5 (3 Packs)

Got these to have spares around, since I always end up needing them. And theyve been good to have around. Quality is on par with what you get on the stock hotend. Do note however that they dont come with any of the set screws. But the heatbreak works great with PLA, and heat block is a drop in replacement as well. Good price.

These heater blocks do not fit the CR-10 V3. The screw holes do not line up.

good parts.

Fit my ender 5 pro with a gulfcoast robotic all metal hotend perfectly. The stock one would not stop leaking no matter what I tried and these new blocks finally fixed that. Quality and finish seem to be better than original so far. Would definitely recommend.

As there are 3 items in the lot, I will split it up into 3 parts: *Silicone Sock - Got the most use out of these things. They work in retaining heat in the hotend. My printer honestly doesnt need it, but it helps in keeping the hotend clean. *Heater Block - Looks like the stock block. Fits well with all-metal heatbreaks. Temperature probe and cartridge have no problems. There were screws for the heater cartridge. I did have some problems with the fact that there are no screws to hold in the temperature probe. Had to use spare screws, but it really should be included. *Heat-break - Didnt use these as I already have a pack of all-metal heatbreaks, but these are still useful as a backup. Overall a good pack of parts. Wish it came with those aformentioned temperature probe screws though.

Mine didnt come with any of the the grub screws that hold the heater in place or the screws that hold the thermistor in place.

Does not come with screws, threaded piece is too long, and there is no nylon ptfe tube on the inside.

The heat block has two holes for screws for attach the heatsink. The holes between the heatsink and the block are not align and there is no way to send a screw through both holes. Returning and looking elsewhere

Replacement parts for my ender 3 pro, works with no issues

The depth for the screws are too shallow. So you need to hit the hardware store to get half an inch linger screws to make up for the fact they dont set 1/2 way into the block like they do on the stock cr10 v3 heater blocks. Just hit up ebay. Amazon doesnt have ONE seller that has the correct ones.
