Printed out, fits like a glove. Thanks for the design.

How does this connect to the printer? Do you need longer screws or are the original ones ok?

I've moved on to one of the other extruders available here, but I've used nothing but the original screws with both extruders.

I think that only 3 of the screws engage with the motor and the 4th screw wasn't long enough but I haven't had a problem with just the 3 screws after many months (and many spools of filament).

Is this with the original wooden extruder assembly? because for me none of the screws are long enough and I'm still using the original extruder assembly.

I'm quite shure that this part does not only replace part L put also part P - the one with looking a bit like a horseshoe (and of course some others on the "beltside"). With that still attached, the skrews will be to short.
I'm planning to print one, but how do you secure the stock hotend without the two M3x30 skrews?

Oh, now I feel stupid. I thought it only replaced parts X, Y, and N. Thank you. Your help is much appreciated.

Sorry, I am a begginer in 3D printing... what orientation you recommend for printing this piece? Thank you!

print it on it's side, with the piece that contains teeth having the angled section near the bottom.

You can't easily print an overhang that large without building up to it bit by bit, hence the slope going at the bottom.
