Good to see you're making progress.
Idea:
The lower filament guide cast it as a second piece.
This will allow you to pull from the mold in one axis, eliminating orthogonal core pins.
To attach it, add 2 holes in the same axis as that of the filament guide,
and from the bottom bolt it to the main part of the body.
To attach it use Hi-Lo Self-Tapping screws.
