Ender 3 To Duet Wifi

It is a tight Fit to get the Duet2wifi in the original controller box on the Ender .
The Wire for the Bed has to go inside the groove in the extrusion in the back, you can choose to whiten the old USB plug hole 28 mm without a reset button and 35mm with the reset Button. the frame has a very tight push fit, I have kapton tape over the WiFi antenne and the LED behind it so it doesn't come in contact with the metal/ground.
