This is probably one of the most useful, yet simple designs I did for the ultimaker, in addition to the XY "bananas blocks". You can read about the list of improvements on http://www.tridimake.com/2014/01/features-and-improvements-for-a-homemade-ultimaker.html
This one makes life easier for sure. Fine-tuning the level of the Z end switch is a chronic issue, especially as you switch among different nozzles or bed thicknesses.
In this design, the carriage slides tightly in two concave rails of the outer frame, which is secured on the case by four outer screws. There is NO way the carriage can move otherwise than vertically, as it should. Neither the carriage nor the micro-switch do touch the plywood for a fluid movement.
Most of what I have tried so far proved to be unreliable in this regard, probably because of something that (tried to) slide against the internal plywood wall. The only parts here that are in contact with the printer walls are the fixed parts.
I designed it for an Ultimaker, but it easily adapts to others. The openscad source code is included as usual, in case a change is needed (here is a very easy tutorial if you need it: http://www.tridimake.com/2014/09/how-to-use-openscad-tricks-and-tips-to.html)
