This is a Remix of Leo_N's great design.
I just added two tabs so this case can be screwed down to the table or whatever surface.
Also with the tabs this can be printed without supports.
(In the picture you can see my faceplate for this LCD12864 Case, but this is not a thing [yet]
It is only a prototype and would need a little more work. It is screwed from the front to exactly the same holes as the LCD is screwed in from the back.
Let me know if you want this as a thing.)
