Great Print...except for...

Anyone have any idea what happened to this last part of the print? Otherwise these came out perfect. Not sure what happened on the tall piece, looks like it had a rough time. First guess would be speed too high for that small an area…??..

It looks like you needed a little cooling on the end. I am sure the layer times were pretty short.

Yep, probably, it almost looks a little cooked.
