Photography Tripod Accessory - Holder for Vanguard QS-39 Quick Release Plates

I have three QS-39 quick-release plates for my Vanguard tripod. They get swapped around between two camera bodies and a few large lenses, so I can never keep track of where they are. Yeah, they're only like $17/ea so buying a couple of extras would be the easy fix. But I was just starting to learn Fusion 360 and it seemed like a good hands-on learning project, while at the same time, the end result would make my life just a tiny bit better. Now, all three plates get put in their slots, the whole thing rubber-banded, and tossed into my tripod case. Come to think of it, I could have done the same thing with just the rubber band and no 3D print… Dangit.
