This is a protective case for the stenographic keyboard Georgi by Jeremy Bernhardt (https://www.gboards.ca/product/georgi)
His product is a great lightweight steno board which works with Plover by Mirabai Knight et al (https://www.openstenoproject.org/plover)
The only issue (which is actually a feature, but for the clumsy me it is a nuisance) is that all the components are exposed.
This case is to protect the SMD components of the board from being torn off the PCB.
Also it keeps the TRRS connector from excessive movement, less chances it gets broken off the plate.
Fusion 360 project here:
Update 20190808: Added photos after the 1/4 mount adapter was added.
There is a spot in the middle of the board without any traces or wires. I drilled 9mm hole put a 1/4 to 3/8 adapter from the bottom, fixed it on top with a nut (model included.)
All that mounted on a stand (Kinect or any camera one with 1/4 screw on top.)
Update 20190808 (2): Added model and photos of the bar holding the halves.
Update 20190820: Added a file with walls raised 2 mm more - the deepest one.
I used support lines to make the removal easier.
The resolution is the finer the better.
You might scale it in X and/or Y direction a bit (0.995) to make it snug fit.
