For some time I have been modifying iamburny one piece hot end. I have incorporated a number of features.
1. 3 vents to distribute the air flow across the width of the head, cooling the filament quicker as an aid to bridging -- tests ongoing.
2. Slots for the heater cables and the sensor wires.
3 Protection of the wires from the aluminium block.
4 Extended and strengthened post to keep the cables high and out of the way
Photos and stl attached if anybody would like to use it.
