    Anyone know what is the size of the bolt that holds the hot end in place? Mine seems to be stripped. Many thanks in advance.

    Mine stripped too, what I had to do was drill out the shavings and drill it clear though with a 3.5 mm bit (I suppose a 3 mm might work also) then I re-tapped the threads for an M4 bolt. I am not sure you will ever find a replacement for that aluminum piece.
