Bally Judge Dredd pinball flipper opto curtain

My opto sensor curtain for left flipper broke for some reason (it's metal, and it snapped!) So I created this in PLA. It clearly was repaired before, so not sure why it's such a wear/tear item, but I'll comment how long it lasts.

This is the thing that flipper button pushes, and it moves away from between optical sensors behind the button, thus registering a button press.
