I live on a sailboat so all of our DJI equiptment MUST have waterproof cases. I was unable to find a waterproof case with a insert specifically cut for the Osmo. So I ended up buying the size of case that I wanted with the pluck out foam inside. Here is my case with the accessories I currently have. I left room for future accessories. The nice thing is if I don't have enough room I can just buy a new foam insert and recut the spces. The case is made by Nanuk and it is their 910 size.
I have Nanuk cases for both of my drones, and these cases are incredibly well made. Customizing the 910 for the Osmo Pocket and its accessories is a great idea. Thanks for sharing this.
