the easiest way here to reduce filesize would be cutting it down to an eigth (0-45°), then use that subfile 8x in the main file...
(that also saves the amount of work)
also looks like the innermost one should be nearly round, the one farther one could be reduced to every second vertex.
(or go something like 12-12-8-8-6-6-4-2 to keep a constant distance)
this part also has an older variant without the stop ring (2164), but the top seems to be the same (except for the dome at the upper end)
did you compare it to the one from digital-bricks? http://www.digital-bricks.de/en/file.php?part=40554

that one looks way coarser than yours, but the dimensions may be better...
also, what about the orientation? tips/ribs to 0° or side to 0°?
