Bracket for the MOSFET upgrade on a Wanhao i3 V2.
The 4 upstands for the MOSFET have a 2.5mm hole in them so you can screw an M3 screw straight in to them
No drilling required, just remove the 4 circuit board screws and slip this bracket over the 2 case studs nearest to the LCD display.
Then refit the board and connect the wiring.
