What I was hoping for ideally was a way to fix it without any permanent changes to the original parts.
This is what I have done for now in the corner worst effected.
The only reason I need to do it at all is that the up arrow does not buckle every time.
The plastic has moved away from the metal.
Its just a couple of hair grips but it has the up arrow working fine.
I would ideally like to find a way to melt the rivets back into place but I dont think that will work.
I might try and make a larger clip to sit on the side there.
Its working OK for now though
