The Blue2 device is essentially a brain and buttons but some people can't use the supplied buttons and instead need to plug the device into alternate buttons. For these people their device would usually sit out on a table or be haphazardly connected to their chair but the device would often fall or settings would be accidentally changed. With this case the Blue2 is securely attached to the chair and all unnecessary buttons are completely unable to be pressed.
I designed the Blue2 Case with a thin layer of plastic which goes under the buttons ensuring that they will never be pressed. There are access holes for the on off switch and pair button as well as the plug holes. Here is a link to the onshape file.
I made about 25 blue2 cases so that OUSD is able to have a 1:1 ratio of cases to devices!
