Fab-Mini Z Axis Stabilizer

After printing the Mini fabrikator z-axis wobble fix (http://www.thingiverse.com/thing:1493285) I discovered that it didn't fit the Fab-Mini version 1.5 which I had so decided to whip up a customizer version to adapt to what ever size someone needs, The default sizes are the ones which used for my Fab-Mini version 1.5 and the seem to work. Worth note, this is just not a "plug" with a hole. The structure is designed to have to [two] center pinch points to minimize contact with the rod and reduce the potential of friction. Second the tapered plug design which creates a pressure fit with out adding glue. Also included is a scaling factor for the material use 0.1 for ABS and 0.2 for PLA and please note this is based upon my experience. Setting are as follows:

** Diameter of top retainer (mm)**
Top_Retainer_Dia = 15; Range: [12:1:20]

**Changes the shape of the top**
Top_Retainer_Thinkness = 3; Range: [3:1:10]

** Thinkness of top retainer (mm)**
Top_Retainer_Shape = 8; Ran
