RepRap Wallace/Wallace++ Compilation Edition

Update: 17/03/15
-------------
### Added y_motor_holder_rack.stl as the .scad file requires the original wallace scad config file.

---------
### Added y bearing retainers.
* y_bearing_retainers_4x.stl
*this is a set of 4 retainers nicely arranged*

* y_bearing_retainers.stl
*one single retainer*

* y_bearing_retainer_stopswitch.stl
*y bearing retainer with an assembly for a stopswitch*
I personally do not use this. This is here just for principle of
completeness.
