Inner cage for PolarPro Spark Soft Case Mini

PolarPro Mini soft case for DJI Spark is nice because it's mini. On the other side, it's soft - so if you squeeze it inside your backpack your Spark may be squeezed as well.
My Inner cage makes sure that your spark will still have enough of space even in crowded environment.
Once printed, just stick on the bottom a piece of velcro (the one with glue is excellent for this purpose) and you're ready to go.
Oh, did I need to mention, that two spare batteries will still fit in the case..? ;)
