hi
i realized adding keys/connectors/dovetails etc is a ton of work
-making the negative, postive key
-duplicate everything and then do the boolean
-turn on off xray all the time, turn on solo to check …
takes pretty long i think to just get one connector the right way…
a few tools for adding keys would be cool…
some kind of tool wich automatically does the above steps..
for example something like in bambulabs slicer wich basically lets u add connections/keys/dovetails when trimming..
when its already trimmed this method maybe also can be archieved with extra masking tool maybe?
i hope its understandable what i mean 
i think alot of ppl would like this
thx
