Here we go:

Keith's hot water method worked a wonder.
I was terrifed the cover would break, but as the pins are shortish the plastic did not have to stretch too much.

These pins are 3.0 mm and are a press fit in the plate that is 4.0 mm thick.
Here is the pin hole and how a 3.0mm drill fits snugly in it.



The plate being 4.0mm and the hole being 3.0 mm leaves a bare 0.5 mm for threading all around.
Fortunately I have a Greenfield set with a 3.5x0.6 tap/die combination which is rather rare as the usual I see (when I see it) is 3.5x0.5.

I was able to tap the holes with just enough threads to be able to put a screw in as the hole is not too deep and I don't have a snubby 3.5x0.6 to get to the bottom.

The threads bit and in doing so actually caused the thin wall to bulge.
But it is not an issue as the screws are not actually holding anything, they only have to stay put and act as a pivot.

I did not have 3.5x0.6 screws so to get by for now, I made ~ 5.0 cm of thread to make the two set screws I was needing.




?
Next week I'll get a couple of proper 3.5x0.6 screws, cut the heads off and dremel in a tidier slot.

@ Keith: thanks again, you saved the? day for me.? 8^)
@ John: thank you for your input.
But there's really no need to get your nickers in a twist over my post.
My opinions are just that: my opinions, to which I am entitled. Just as you are entitled to yours.
Mine are solidly backed by over four decades of professional activity in my specific field which, BTW, include design and QC.
Do have a good day.? 8^)

Best,
