Here is a list from my created_parts directory. They should all be in the forums somewhere, but are probably (mostly!) not as good as current standard because many predate the creation of the parts check script. Many of them I don’t remember making, some of them may not be mine and just in the wrong directory 
. Then there are a bunch of user submitted parts that I have fixed up over the years that aren’t in this list (and because they aren’t mine, aren’t mine to submit to core either).
