Most DSLR cases or backpacks would fit the Macvic and accessory as it is so compact. I got a backpack which holds all Mavic components, will hold a laptop and a Ipad Mini and still have some room to spare.
I've been using my LowePro Fastpak for my Mavic lately. I've had this pack for probably 10yrs now and it's been used on so many trips and adventures. The quality is outstanding and I was able to configure it to fit the Mavic nicely. I do notice that LowePro is making a bunch of bags that are purpose built for drones.
