Wanted to have an easy way to transport all my equipment when I want to go out and fly my quad. I had an old backpack tucked away that could fit my remote, googles, tools, batteries, etc. It just needed a way to safely and securely attach the drone, so I just quickly designed a plate, printed two of them, punched out holes in the backpack's fabric, and used three bolts/nuts to firmly attach the plates to the front of the backpack. Works great for jumping on my bike with my gear to go out and fly in open areas!
