MJX Bugs B2 battery compartment cover (remix).

This is remix of https://www.thingiverse.com/thing:3003096 (very useful design, thanks for sharing). I needed modified cover for non factory battery. Original design has easy to break door latch, so i changed it to separate element (flat printed for more strength), mounted on M2 screw with nut. Printed in PLA, 0,2mm layer, no support.
