all you need is unscrew propmount, cut ring from thin film like this  TABpro protective film, put this ring (3) between two plastic parts (1)  and (2) and reassemble prop mount. thats it. it will hold your propeller  firmly as it should do. no foam (does not remove vibration) or any glue  (temporary) on the props needed.
just try this and please report here)

meskal, that is a cool little fix! Very simple and inexpensive. Safety First! Ken.

great idea but wonder if you can use a regualr phone protector. ya know be smaller, less waste, and cheaper. or maybe even the plastic they 90% of stuff is sold in now-a-days, you know that plastic clam shell you gotta cut open and hope you dont cut yourself

Flight safety is always the top priority! Take care and fly safely.

Diana,  if flight safety is always a top priority than why hasn't DJY addressed this problem to correct this defect?

Because rattling props are not sacrificing Inspire's flight safety. Once powered and off the ground, up-lifting prop thrust securely hold them tight against locking mechanism, eliminating any rattle. To my knowledge there was not a single reported case of Inspire 2 props disengaging during even the most brutal acrobatics. It's nothing more than cosmetic nuisance.

I don't know if it's somehow related to the OP, but look into this thread

Surely related.
Imagine if somebody very interested in selling quick release mounts for USD200 or sets of mounts+props for USD300.
how to make a good quick little promo of this product, free of charge?
just crash oem prop mount with plyers, make picture of it and post here and there in DJI forums and FB groups.
after that post comments like: "Thanks God, both my Inspires are equipped with T-Motor CF props".
you are done)
