I might want to know why the hole on the left flange needs such insane tolerance though. Maybe it's not relevant in a specific version, or maybe I have an idea for how to solve the issue so it can be made cheaper, etc. Maybe it's absolutely integral to the whole application and I should stop wasting my time trying to make a printed PLA version, etc.
