I've been looking at a lot of USB-C connector protectors for my phone, as it's a weak point for me; that connector always seems to break. But the ones I've printed either don't fit properly or are too thick on one side and too loose on the other. So, this is something simple to make, and I did several tests. This one fits perfectly and is very thin. I hope it works. Printed on basic white TPU. The parameters are in the 3mf file.
