Upload the universal gcode on an SD card and insert it in any printer. Launch the gcode from the printer interface, ignore warnings and proceed. Adjust temperature and fan speed once the print starts to fit your filament needs

Printer requirements for the gcodes: preferably 0.6mm nozzle and at least  180x180mm buildplate

Haze Fits any 120mm PC fan

Cut the fan frame with pliers and attach it mid-print with thick double sided adhesive tape.

If you choose a USB fan, you can add a "usb fan speed controller" (Google it) to adjust and increase USB fan speed.
