Hey guys. I have the side shot phone mount. But I want to use it with my go pro 7 to record slowmo. Where do I buy the go pro case to mount to put on my side shot. Do they make a go pro case and sell it separately from the side shot so ppl with the phone mount and just take it off and replace with the go pro case without buying to whole set up which is 279. Vs maybe just buying the case for $40-50.
