I had a monitor arm that I wasn't using so I decided to mount my new Sonic Pad to it.
The bracket is symmetrical so print 2. Technically one is strong enough to hold it but 2 looks better. Separate versions for 100mm and 75mm hole spacings.
The Sonic Pad stand legs need to be removed. You can use those two shoulder screws in the bracket if you want. If you want to add 2 more screws they are M3 x 8, either button or cap.
The mount to the Vesa plate is done with (qty 4) M5 x 12 screws and M5 nuts which press into the hex cutouts.
This bracket locates the screen in the center of the Vesa plate. There is 2" of clearance for the connectors and cables.
I have another design in the works that mounts the pad up higher and without a 2" gap so the connectors are above the Vesa plate. The bottom half of the plate is visible which is kind of ugly but provides a place to mount a handle, tool holders, USB stick holders, etc. Still working on that. Maybe a Gridfinity mount?
