Hi there!
Are there any aftermarket replacement options for heat block used in Snapmaker 2.0?
I’ve been using 4 hot-ends since I’ve bought Snapmaker 2.0 last year and it looks like it’s too many 
I’ve disassembled two faulty hot-ends and it appears that stock heat blocks are made from too soft aluminum alloy and high temperatures are not making them stronger.
Can you post some pictures of what happened to the heat blocks?
I didn’t see an aftermarket option yet,
Sure!
Here is photo of mine stock SM2 hot-end with unscrewed nozzle.
I’ve bought some Volcano-based heat blocks because they are pretty similar in dimensions with SM2 hot-end, but they are in transit.
That is some damage… Looks like you crank on it pretty hard, I go easy on them, just snag and then thermals do the rest.
I thought volcano heatblocks are somewhat vertical design. The filament path is twice as long as t is in the stock heat block. 8.5mm vs 20mm. If this is one you ordered, you won’t be able to use the autoleveling and it might crash into the bed since the offset is so different.
Yep, unfortunately the nozzle didn’t get out without applying pliers, although the hot-end was hot…
Thanks for sharing your heat block option - will try that out too.
I mocked up the v6 heatblock with sotck parts and aftermarket, looks like using stock parts, 3mm would have to be shaved from the top to connect stock heatbreak and stock nozzle.

With aftermarket heatbreak and nozzle - no gap in the middle but about 2mm would have to be shaved from the top to free the transition zone.

It’s a tight fit, but possible. A little too close to fan shroud tho. The wires are probably would have to be elongated.

Did you get around to try?
Was busy at work so didn’t have a chance to adapt newly purchased Volcano heat blocks.
Curious if you got to try them out…
