Inspired by https://www.thingiverse.com/thing:1827416 design @FunctionalDesign .The _ring file could be easily changed as you wish, Fusion file is only for the clip. Actually, I'd recommend making the hole in place of shaft and design and print shaft solid, separately.
Second thing, depends on tolerance/ precision of your printer, you'd need to apply a bit of heat on the bottom of the clip, fit it and hold for half a minute, works like a charm. I noticed, shaft printed on mine has not a tight fit, a bit of masking tape solved it.
