Docky-bottom added width

I really like the docky but the screw holes in the bottom plate are a little too wide. The wall thickness ends up being 0.38mm which can give you some issues with certain slicers (cura for example).
I added 0.2mm of meat on the right side, your bottom plate may not fit 100% but at least the wall is completely printed :)
Part may need a little bit of force to push into the top part. printing this right now to test the result.
