The case looks like an Apache 3800, available at Harbor Freight Tools for $40. That plasti dip looks like it does a fantastic job. I may have to pick some up. My other 2800 is laid out for my Mini 2, but with seat cushion foam. I can think of a lot of ways to use the plasti dip. Thanks for the tip.
For the ones that are looking for the 3D sunshade print file for the RC Pro.
Here is a free version of the STL file. You just need the hardware to attach. Mavic 3 Cine RC Pro Controller Sun shield by chrishornby
I printed this one myself and it works very well. Just not foldable for storage.
