A quick VTX connector mount plate that I made for the Storm Loki-X5 frame. Slides perfectly over the standoffs in the back. Has a hole in the bottom where you can sneak out the battery connector.
I have only tried it with the TBS Unify uFL to RP-SMA pigtail. It might, or might not, fit other pigtails.
I printed this with ABS, but other filaments may be suitable as well.
