Replacement zip pull for my Tripp suitcase. The metal one that came with the suitcase fell off so I designed my own to replace it. It's a little thicker in places but it's a near perfect fit in the provided lock.

I print 6 walls for a strong print, theres only a single layer of infill so it's practically solid plastic. I use PETG-CF for some extra strength and it feels very sturdy, I'm sure standard PETG would be just fine.
