Evo air purifier

Upload the universal Evo.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

Evo works with 120mm fans. The frame of the fan has to be removed by cutting with pliers. Then the fan is attached to the cap mid-print with thick double-sided tape.

The best fan is UpHere, which is smaller then usual 120mm fans, that is why there is a custom "uphere" version of Evo. If you choose a USB fan, you can add a "usb fan speed controller" (Google it) to adjust and increase USB fan speed.
