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

This item installed easily and works fine. I am very satisfied with this product.

Works as advertised

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 is not fully compatible with a standard Ender 3 heat sink. The photo shows my old healer black which clearly has two screw holes on either side of the screw in for the heat sink. These two screws go into the heat sink and secure the heater block from rotating. This product DOES NOT have these two screw holes, so I returned this product and just got an entirely new assembly and successfully replaced it. Please be careful if you have a stock Ender 3. I dont know the situation on the V2, Pro, etc.

Its a direct replacement for the Microswiss unit but be mindful that the threads for both the nozzle and the heater rod can strip really easily. Thats actually why I needed to replace it, the threads of the nozzle stripped out and it was ruined.

Needed a replacement heater block and this is working great on my micro Swiss hot end

Great replacement for Micro Swiss all metal hotend.

This fits the Gulf Coast Swiss hot-end clone, too.

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.

Great upgrade, I accidentally stripped out my original MS heater block so this was a quick swap.
