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

I just had to leave a review for the team at Micro-Swiss. Recently, I managed to shear off my 0.4mm nozzle (noob mistake, never loosen a used nozzle while cold) and managed to break it off in the heat block. This resulted in my replacing my original Micro-Swiss heat block and nozzle with a cheap brass/aluminum combo I had lying around. NOTHING BUT GRIEF. I finally realized what I did in that moment of pique and ordered the $25 worth of new heat block and nozzle from Micro Swiss. Long story short - ALL PROBLEMS SOLVED. I print typically on PETG and PLA, and sometimes TPU with an 0.8mm M-S nozzle, and things are back to being PERFECT. I dont normally get so emotional in my reviews, but Im really appreciative of this company and their dedication to quality. My current setup is: Micro-Swiss Ender 5 Direct Extrusion Head, All-Metal Hotend, 0.4mm hardened A2 nozzle.

The stock ender v2 hotend has 2 bolt holes to stabilize the heatblock to the heatsink, these bolt holes are absent on this heater block (I thought the two bolt holes shown in the image were the aforementioned stabilization bolt holes, however this is to secure the heater cartridge)

This is a great upgrade to the printer.

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..

I didnt realize this does not have holes for the two bolts that stabilize the block on the Ender 3 V2. Now I may have to hold the block while changing nozzles, which will be tricky with the v2 fan shroud. I may have to send this back.

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

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.

Great replacement for Micro Swiss all metal hotend.

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.
