Ryze Tello Prop Guard Holder

The prop guards for the Tello are great for indoor flying but when outside it's more fun to fly without them. The only thing is, what do you do with them when they are off? I tried an elastic band, snapping them to a pen, but it never really worked that well.

This seems to fit the bill quite nicely. The guards pop on and off quite nicely and I've added bumps similar to those on the props of the tello to help with alignment when they are on.
