A case that can be printed in 3 parts (plus a stop button) allowing convenient mounting of the controller on a flat surface. There are many cases for this controller, but none that did exactly what I wanted. I got inspiration from [https://www.thingiverse.com/thing:1562144](https://www.thingiverse.com/thing:1562144) but it is designed to be picked up rather than attached to a surface.

I also used (and have included) the STL from [http://www.thingiverse.com/thing:302196](http://www.thingiverse.com/thing:302196) as the basis for designing the case.

UPDATE: After printing and assembling this thing, I think there are some improvements that could be made:

1. The Smart Controller that I have has the screen PCB mounted a couple of mm closer to the main board which, so I would make the screen surround to be slightly more flush.

1. There was also not quite enough clearance under the rotary button, but I just pulled the button cap up slightly to fix that. If the top was more flush with the PCB, that may solve this issue too.

1. The pillar that holds the screws wasn't strong enough and broke when I overtightened the screw the connects the end caps together. I fixed that by friction welding the end cap back on. I think if I wanted to print another one I would update the design so that the end caps just clicked on rather than screwed together.

1. The original model of the controller board didn't have the through hole components protruding on the back of the board, so I neglected to make allowance for them. This is potentially a problem with the rotary button that has quite large through hole tabs. I just snipped the tab that was a problem a bit closer to the board and it actually is good for it to press against the bottom of the mount to give it a firm feel when you click it.
