Why not use a metal cap from American Radio Supply? See:
https://www.americanradiosupply.com/microphone-connector-cap-dust-cover-most-all-ham-radio-transceivers/
fits the mic connector on the front of the rig.

Why go to the trouble? Metal and plastic caps for SO-239 are available all
over for a small price.
The only reason I can see to 3D print it is because one wants to justify having
the printer

Just found a really nice looking SO-239 cover design for 3D printing on
Thingiverse.com. https://www.thingiverse.com/thing:4854560 It just so happens
to fit the threads on the 8 pin microphone jack used on the K3, and many other
radios.
For those like myself who operate 99 percent CW and don't even keep a
microphone connected to their K2, K3, K3S, K4, etc, this is a useful item to
protect both the outer threads of the jack and keep crud from entering the pin
area.
With the proliferation of 3D printers in many ham workshops these days, if you
don't have one, it should be relatively easy to find someone who has.
