I think I was pretty proficient with my tools but most of the work was measuring out everything and then the first few prints either fail or were not designed correctly so it just becomes a big process that wasn't worth it if printing and CAD are not your passion.
I empathize with this... I designed and printed up a mating door bracket assembly . Lots of time spent measuring, designing, and multiple rounds of prototyping to get something that fit AND worked as expected. I was satisfied with the end product but not the journey to get there.
