No friends with a drill press?
Respect to you!
I would have printed the on paper where to drill, sticked the paper on the panel with masking tape, punched the hole centers and let it go.
OR (crazy mode)
Use the 3D plastic part to design a little fixture for the terminal to install
on top of the original panel.
Those holes will remain behind the fixture so they could also be sloppy...
I mean so much perfection and then you got the chinesium stickers on the panel. Boooo
You should have those text (Sense +, Sense -, Current, V+ and GND) on the 3D part, exactely how you did with "K3706" text.
Of course then masking tape again to spray paint the text properly.
