Do you have six PolarPro filters for your Mavic Pro? Their original case is somehow large, so here you have a case that utilizes original foam (30x30mm cut-outs). Filters will feel like home, while you will save a bit of space.
If you have this small everytnihg-proof case like B&W offers, this case fits nicely where charging hub usually sits.
I have divided hinge slots on one side, as it prints better that way - all you need to do is print two additional "halfpipes" and glue them afterwards.
Hinges are prepared for 3mm axis (material of your choice, I used carbon rods) - depending on your printer, holes may need drilling out a bit to proper inner diameter.
