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

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..

Made of titanium. Swiss is the only hot ends I use. Well packaged!

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.

How do you attach it to the heat sink without the two holes? The two holes used to attach to the heat sink are missing. I thought it would work by pressing it in firmly, but it came out on the first try. I liked the looks of it when I ordered and I ordered three. Am I going to have to return all of them?

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

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

Awesome upgrade for any compatible printer. Beware it seems to work better at about -5c from your normal temp before this was installed (for me)

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.

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.

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
