28mm Spinner caps male/female

Most caps are press-on, but I find it hard to get the size right to tightly fit on my bearings. These caps are male/female so allways fit no matter what your filament error is. Within certain ranges of course.

I already found the 20mm ones and I liked them, but wanted to have 28mm as well.

There's a 0.1 mm radius clearing between male and female part.

I updated the parts so that there's a little more clearance between the flat of the cap and the bearing, since we had the cap rubbing the spinner a little with the first attempt.
