given the odd size (its even bigger than the yeti) you would likely need to use the official one as finding cheapos will be hard. the same is true with the yeti.. its so huge that i'm not aware of a cheap mount for it.
for an arm, given the weight of the mic i know these should work well since they handle a yeti https://www.amazon.com/RODE-Swivel-Mount-Studio-Microphone/dp/B001D7UYBO

you might be able to get away with this on the cheap if on a budget or some of the others but they are lighter weight...

you may or may not need thread adapters. for some reason they like not listing thread sizes when buying these things... its normally one of two common sizes and adapters are dirt cheap if you do.
as for pop filters, you can get the official razer one or one of the other various models which clip on to the shock mount or boom arm. any of those style should work.
