Sometimes I try to plug in a USB plug, get it wrong, turn it 180 degrees, get it wrong again, turn it back around, and then it goes in. Despite only having two sides lol
I've found lots of things are fumbly like that. Part of the reason I suggested measuring it. Sometimes if something doesn't fit, I'll measure it, find it identical, and THEN it'll fit. Don't ask how that works. One of life's mysteries.
