I found my POM arm inserts to be a tight fit. After some fiddling I could just get them seated but couldn't push them further. Theres some M6*16 Cap heads in the kit you can use to give the thread a bit more reach to pull them home.
I also had trouble with the sizes on this one but persistence payed off, might pay to clean up the bridges/sacrificial layers in the shroud to give you an extra bit of distance if you have issues.
It’s not possible to slide the M3x20 (next step) in behind the cable strain relief. Instructions would be better to suggest to locate everything but leave the tightening till after the arm is attached to the rail.

M3X10’s should actually be M3x8’s according to onshape CAD files.
