I have purchased an all metal hot end from Micro Swiss, it looked correct at the time as my CTC has the smooth neck which is held in place with a grub screw in the aluminium mounting bar.

As I'm sure you all know, the Micro Swiss hot end uses an M7 nozzle thread instead of the M6 which most use. 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.
