I don’t think that is a good idea for two reasons.
1-Your files might not be correct (and you have modified them).
2-These parts are fairly simple (No surfaces or other “advanced” techniques needed), if someone can’t model them they probably should not be modifying them. I always give out a critical dimensions to anyone who has asked.
I hope that doesn’t make me an a**hole, I just don’t want a bunch of “upgraded” parts showing up. This happened when I first released it and it was honestly a nightmare for me to deal with. Lots of tech support for poorly made things or awesome parts that just were not able to be printed. I am okay with any parts going to thingiverse in STL form but making it a little too easy to edit is probably not a good idea.
