Hi,
i have a I3 Pro B, originally with the plastic feeder.
I've ordered the Alu one and i just build it, but i have a problem fitting the whole Mk3 Back in it's place on the printer.

The spring screw on the bottom of the feeder has no place to stay on the plastic of the printer. I mean, in the plastic that holds the hothend rod's hole, there is another hole, but the distance between the 2 holes is less than the distance between the feeder hot end rod hole and the screw.
As you can see, the screw on the feeder cant fit any place on the printer's mk8 placement

Why?

Hum, after some more thinking, i figured out that maybe the plastic plate has to be removed because it was part of the plastic feeder.
On the metal plate under the plastic one, there is a screw hole that is right for the screw on the feeder.

To be sure, i need the right hex screwdriver (bigger than the one i used for the other screws). I'll get it tomorrow.
