Elegoo Neptune 4 PRO Extruderhead v2

When i designed this printhead i had a few things in mind: -quiet down the printing, -integrate the 40mm fans in extruderhead, -more space inside the head to direct the wires and heat dissipation -more clearance around the nozzle to see the print better, After installing it is whisper quiet. I used PLA Print with the backside on the buildplate 0.16/20 layer height auto support needed infill “”GRID" 15 % or own choice use 3x40mm 24v fans from Aliexpress
