This is a simple box for an Inductrix FPV+ Drone. This is very similar in concept to this case for a Tiny Whoop: https://www.thingiverse.com/thing:1580567. The interior of the box has slots for three batteries. One space is left open for the battery charger. It's a bit bigger and requires no additional support - it's held in by the fan housings. There are two STL files: one for the box and the other for the lid.

NOTE: The STL for the box is may load into your slicer upside down. Please orient into the upright position before slicing.

I attached the Fusion 360 file, which has the text "Inductrix FPV" embossed on one of the faces. That's easy to remove in Fusion 360 if you prefer not to have it.
