CrazE Wing Bottom Skids

I enjoy flying my CrazE Wing, but the covering is quite fragile, so I printed these skids for the bottom when I have the possibility of landing on a rough surface. I made them easily removable. I put the notch in the bottom of the middle skid because I use a rubber band to add a second hold down for the hatch. I don't trust the weak magnet. The middle skid is secured with a few small pieces of double-sided tape.
