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 240x240mm buildplate for Eno 200mm, 180x180mm for Eno 120mm

Eno sliced with Bambu Studio has slightly different infill pattern with same functionality.

120mm Eno Fits any 120mm PC fan, 200mm Eno fits Noctua NF-A20 5V USB pc fan

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

"Uphere" is smaller then usual 120mm fans, that is why there is a custom 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.

For higher Noctua fan speed, use a “12V motor speed regulator” with a “12V power adapter”
