I needed a case for the foam packaging that the DJI Mavic Pro's ND filters come in. Nothing fancy, just a snug case for some decals. :)
I needed to scale up the design 2% larger when printing to get a perfect fit so you might need to experiment a bit as the foam may not the cut to same dimensions to everybody.
Model is solid so print in vase mode!!! Worked for me with Simplify3D.
3 solid layers on the bottom.
