Stadium Seat Spacers

I would Always get annoyed at ballgames, because me stadium seat's locking arm had way too much gap in it, causing it to lean back too much when I tried to use the back rest. So, I can up with a solution. it is designed to work on a 7mm swing arm and is stackable, so you can make it fit the whatever stadium you are in. You might want to print a few of the middle section.
