I managed to measure mine, and got 15 mm +-0.02
My UM2 is about a month old.

I have just print it and the diameter is perfect for my new UM2

I'll do that, I just don't have a way to measure it accurately enough. Can't find digital or dial callipers from any of the local stores, so I'm converting a printable set from imperial to metric, it's about half way printed but the reduction in scale to convert it to metric has made it a difficult print

Just printed these, but I had the opposite problem - they were too big, but by less than a millimetre I guess

Too small by maybe 1mm diameter.

Thanks! It works great, but I had to use a small heat gun to get it mounted.
