I have download a PCB footprint from a vendor that includes a STEP (.STP) file of the part. I have added the footprint to my personal footprint library, but where can/should I put the 3D model file in order that it not be overwritten by future KiCad installations? I use KiCad nightly releases and I that see KiCad defines the path KICAD6_3DMODEL_DIR, but I suspect anything I put there might get blown away by a new install, which for me would be every day (max.).
Anything that is not in the "official" libraries should be in *your* library store. Create your own library tree in a place of your choosing. Then you can define KICAD6_USER_3DMODEL_DIR, for example in the KiCad > Configure Paths dialogue. Do the same for KICAD6_USER_SYMBOL_DIR and KICAD6_USER_FOOTPRINT_DIR, etc.
It is often said that you should only use symbols and footprints that you have personally verified as being suitable for your specific purpose. Even if you don't change what's in the Github libraries, copy it to *your* library, then it won't change without you knowing about it.
