Saw a 9mm blank gun loader for a single stack magazine and used the idea to create a similar one for S&W double stack mags (https://www.thingiverse.com/thing:3379178)
Fits a little tight on some mags so you may need to do some fitting on the inside (or let it wear in).
You will need a spring and a roll pin or screw to complete
For the roll pin, use a 1/4" #10 or M5 button head screw if you don't have roll pins.
Body - print with 1mm or greater walls so that the roll pin is well retained.
Plunger - print with 1mm or greater walls and a 40%+ infill for strength.
