Item not as described. The drawing shows a 60-70° chamfer on the input side and a very small on the output. The Input side is full of burr and 45°, but the most problem is a gigantic 2mm chamfer on the ouput side. The material moves in the gap and clog between the heatbreak and the hotend, caused by this stupid chamfer. All 5 pieces goes up into trashbin.
Everything is fine, good quality item. Shipping not that fast about 1/5 month.
