Nerf Rival Nemesis Battery Cover

Replacement battery tray cover for a Nerf Rival Nemesis. Remix of a file off Thingiverse to clean it up and make adjustments like increasing space under the cover. No cutting needed, fits right in place of the original. Does need a new M4 screw to hold it, at least 25mm. 

The “plain_thickened” isn't tested but adds a bit of wall thickness near the back corners to account for slicing tolerances. Fits on a Prusa Mk3s plate when rotated about 55deg. Needs plate supports only for the tab. Should do at least 2 walls but not much infill is needed.
