Cant find the specific printable part for extruder I need
Hopefully this is an easy find and I'm just blind, but I need help.
So I came in one morning to find my extruder had melted. Honestly not sure why, that's a topic for another day. It'd been working for months prior with very few complaints.
So anyway, I had my friend (who also has a prusa) print me a few of the replacement extruder parts that had melted and today I went to reassemble it. Which is when I ran into my problem:
I have an mk3s with an mmu2 on top of it. So I went here to download the parts we needed. Problem is, something is slightly off about this particular part (the extruder body):
At first glance it looks identical, but up top its slightly different:
and its to fit this orange piece, which I believe replaces the steel ball holder thing (I'm assuming this is because of the mmu?)
So I guess my question is: where can I find the file for the "correct" extruder body? And/or is there a reason it's different? Should I use a newer version or something?
Hopefully that question was clear, thank you!

I think you will find what you need here
Sorry for my poor English. I try to do my best.
RE:
There are no changes to the extruder body when upgrading an MK3S to the MMU2S, thus I suspect you may have chosen a part for an MK3S but own an MK3S+ or vice versa; both part sets are available on the site you have linked to.
BTW and since you´re reassembling the extruder anyways, you may want to consider using instead a much improved body by The Zero Beast, to be found here: https://www.prusaprinters.org/de/prints/66215-tzb-mk3smk25smmu2s-extruder-mmu2s-no-tower-v3
It is supposed to have a much more reliably working filament sensor in connection with the MMU2s.
Just make sure you print the tower in black, because any other color (such as orange) will be partly transparent and disturb the filament sensor.

@manelto The extruder body in that link is the same one I printed that is not the correct replacement.
@justme3d Thank you, that led me to the right file. The file I am replacing is the part from an MK3S , not an MK3s+ which is where i was looking.
