What is the best way to make these extrudes?

Hi there, I have a question that I'm wondering if the crew knows how to handle.
https://cad.onshape.com/documents/e9ce8b78cb91236aeb21848e/w/ca92b271a72e279056f0fa94/e/4ea38a2a28a99ec078af07f5?renderMode=0&uiState=6695b9d5d6c64a295301c078
I have these holes into which I plan to slide some nuts. This is a common technique in 3d printing where you fasten two parts by putting nuts in one and screws in another. In this case, I've used an M3 clearance hole through to a given depth in the second part. Then I drew the profile of the nut on a sketch and extruded from the bottom. Finally, I mirrored the extruded faces across a mate connector.
So, the thing that I'm wondering about is that getting all this set up was a little tricky. I initially tried to use a feature mirror, but that only worked across the first mirror plane. Once I tried mirroring the mirrored feature, things fell apart. It seems like reapply features can only tolerate one mirroring before things get weird. Maybe a pair of mirrors would have worked better than one if I were working with faces.
The bigger objection I have is that the extrudes were so much more fiddly to set up, with mirrors, than the holes were with linear pattern plus. Is there any way to make this type of nut-slot easier to build? The image below shows the extrudes I am thinking about, in case it's not obvious from the link:

In my model I eliminated the pattern of the countersunk holes, and only extruded one nut slot. This series of features was mirrored, then these features (plus the first mirror feature were mirrored again.) I think it looks right?
Can be done in one feature with the multi-mirror FS:
