Changing the size of snaps?

I’ve recently been given a new computer at work and I’ve noticed that the snap points [whether green, purple or any other colour] are now tiny - almost too small to see. I was wondering if anyone had this problem or knew how to make them larger? I’ve done quite a lot of googling about this but not come up with any answers. Thank you.

If you search for Inference points retina you’ll find a download for some larger versions…

They use Image files so I just cropped and set of copies and Steve posted a zip folder and instructions…


Thank you for this, it worked perfectly - and I’m very impressed by the speed of your response!
Obviously I was searching for the wrong thing.
