I have bored the mounting hole in the upper aluminium bar from 6mm to 8mm and now the upper part of the hot end fits nicely. But I now need a new heater block with the correct M7 thread so that I can use this hot end.

Does anyone know of a source for a mk10 heater block with the correct M7 thread?

Thanks.
I've used these from Qidi Tech with the Micro Swiss all metal hot end for a MK10 style extruder on my CTC.
Be aware that there Thermal couples may have a different thread size then normal.

But there matching Thermal couples are pretty cheap
