Fan Cooler for material just printed and upgrade for Hot end cooler.
This sistem was tested on my Prusa i3 Bowden extruder.
I work until 32hours continuosly for three sequence and never stoped.
Material use was PETG so hight temperature.
I sudjest to print this Fully density 100%
I Upload also G-Code File Settings:
Hotend Temperature : 225°
Bed Temperature: 65°
Time for: Harley_Side_Fan_DX.gcode - about 3hour 10minutes
Time for: Harley_Side_Fan_SX.gcode - about 2hour
Alunar PLA - PETG - ABS -
Best if you can print with 100% Infill Density
