Micro Swiss Heater Block Upgrade with Silicone Sock for CR10 / Ender 2 / Ender 3 / ANET A8 Printers MK7, MK8, MK9 Hotends

will buy again

Am sure this heater block will work just fine, I have never had any issues with Micro Swiss products. I dont like packages, that have been cut open. You never know what has been taken out or put into it.

This heater block works great! Just dont try to clean gunked up filament out of the threads by using a tap unless you know what youre doing..

Just remember you dont get the thermal tube that goes into the top of the block. That comes with the original hotend. That said, I explained my problem to the sell and they were nice enough to send me a new tube.

I stripped the Allen screws on my previous microswiss.. this replaced the nozzle without having to replace the entire hot end. Good part.

I had a brand new Micro-Swiss all metal hotend that I had purchased just after Christmas, but I didnt get the nozzle tightened enough and ended up making a real mess when one of my print jobs failed. I took the hotend apart to clean it up, but found that I had stripped one of the screws in the heat block, so I couldnt get the ceramic heating cylinder back out. Fortunately, I was able to purchase just the heat block. Installation of the heat block was a breeze (after running a new heating cylinder through the cable bundle and screwing it into the mainboard, but thats another product review). Prints great! Currently printing a Mandalorian helmet. Highly recommended.

Just looking at it, you can tell its better than the cheap Chinese made heater blocks you get in a 5 pack for a couple bucks. The heater block is machined well, the threads are all clean and burr free, and it does a much better job holding in the heater cartridge than the single set screw style heater block that came with my Anet A8. The printer seems to have an easier time maintaining nozzle temperature. I dont know how much of that is due to the better design, or the fact that this comes with a silicone sock, but either way Im happy with my purchase.

So glad to run across these parts. Thought for sure my Makerbot Replicator 2 was obsolete! These parts has revived my printer to a new higher quality of printer. Thanks

Burned up the heater cartridge and then stripped out one of the screws trying to replace it. This was the exact part I needed and looks exactly like the original microswiss heat block.

Great replacement for Micro Swiss all metal hotend.
