X motor mount with Integrated Limit switch upper

I wanted to use Banholm's design for the X motor mount but after printing it I noticed it wouldn't work as the limit switch upper was in the way.

Originally remixed from this, you'll need to download that for the other half: http://www.thingiverse.com/thing:1730523

I integrated the two and replaced the text (the a's were incorrect on banholms original).

I also remixed ThingiRob's limit switch too as it was slightly off. I beefed up the brace as 1mm was a bit flexible.

The limit switch is attached to ThingieRobs brackets: https://www.thingiverse.com/thing:1457449

Use a spring on the adjustable screw to give it tension and stop it moving.
