2pcs USB to 3Pin/4Pin PWM 5V USB Fan Power Adapter Cable with Switch, USB to 3pin/4pin Fan Adapter Cable with On/Off Switch
This USB-to-fan adapter cable is what makes the whole mod painless. It plugs right into the fan connector and gives you USB power plus a handy on/off switch, so you can run the fan from a charger without messing with the printer’s wiring. For me, that’s the difference between “easy mod” and “why did I start this.”
