This is how the hot end is supposed to fit in the instructions by Kossel. The hot end should snap right into the recessed hole. In my case, the recessed hole is slightly too small.
Would that pose a problem to printing? THe hot end might have slight tilt and might not be super stable also because it'd be held by the 4 screws from that piece of plastic with the recessed hole that is connected to the rods.
Should I instead go and enlarge the recessed hole such that I can actually fit this hot end snug?
