@obsidianspider I suppose a smooth, injection molded part would not bind up the same, right? I wonder if there is a workaround for smoothing out this area such as a coating of epoxy or bondo that could be sanded nice and smooth without enlarging. Tedious and tiny, I know. Another thought would be to try a set of buttons you don’t care about and remove the orientation tabs. Maybe it’s the angled spots where the tabs are that bind up.
