[Renate]

So, I tried out a proof-of-concept for a holder that hangs off a gooseneck.
The main plate is 7" x 3" of 1/8" plywood.
The bottom rail is a bit of the square section off a Chinese plastic chopstick.
The mounting hole is 1/4-20

I'll have to test it a bit to see how I like it.
I like how this requires no modifications to the Poke 5.
The front cover simply folds around back over the main plate and it's enough to keep it from tipping forward.

I'll probably spray paint it black. Done. And a bit of fine-tuning.
