Retroid Dual Screen - Mini Button Bracket

This is a rough version of a button bracket for the Retroid Dual Screen Add-on when using it with the Retroid Pocket Mini.  

It enables use of the power and volume buttons when the bracket is attached and the shims are put in place.

However keep in mind this is a rough draft and could benefit from someone with more expertise in handling buttons - specifically in creating a model with buttons that can be held in place =).   The way this works now the shims are not held in place by anything so they can easily fall out.

So with that in mind, please consider this mostly a scratch pad where I've worked out the rough placement and sizing for things to function well.  

And please feel free to expand on the idea and create an improved version if you find this helpful to work from.
