Battery cage for Snapper 7

After the last flight with my Snapper 7 I realized that my solution with velcro on 3m scotch tape is not very good. My battery was ejected in mid-flight.
So I drew a cage for Snapper's battery in SolidWorks.
I envisaged the place of attachment of the rubber band and the bolt holes at the bottom, so that the cage does not move from the vibrations.
I think it turned out quite well, replacing the battery now occurs faster and the battery is more protected from crashes. Printing takes about 20
