This is a back cover for the X-Lite Pro that contains a holder for a magnet inside to provide a storage location for another magnet to attach to. Being able to attach a magnet is useful to store the magnet to turn receivers on and off that use magnetic switches. There are no metal areas on the X-Lite Pro or S mode to store a magnet. To use this feature you will need a 3x6 mm round magnet for the magnet holder.

I also included a hole to push a wooden barbeque skewer in to attach a streamer to use as a wind indicator for use to indicate direction and strength of the wind for sailplanes before launching. You can get the barbecue skewers usually at local grocery stores. The ones I bought are bamboo and have a diameter of around 2.87mm. I got a pack of 50 for $1. Just get a small piece of mylar and glue it onto the end of the wood skewer with hot glue or tape.

There can be differences in printers so if the tolerances are not good for the print and it doesn't want to slide with only slight pressure, then don't force it because you don't want to break the small tabs on the X-Lite transmitter that hold the cover on. I haven't experienced any issues with it but you should be careful. It is important to use the 0.1 mm layer height.

I have not tested this to see if the stick or the 3d print breaks before the tabs on the xlite do. if you were to try bending the stick until it breaks. I haven't had any issues with it and bent the stick back pretty far without issue but I haven't bent the stick all the way back to see if it breaks first.
