Autolevel Probe Mount - Printrbot Simple 2014 / Makers - improved

Improved Z probe mount for the extruder carriage for those of us who can't mount on the back side of the carriage due to the new fan placement. Holds 12mm diameter induction proximity probe (plus new version for 18mm probe - but see notes!). Mount attaches via the two hex screws underneath that hold the extruder in place, and via extending the tie wrap location on the corner of the platform. A hole is provided on the extruder plate edge to firm it up by adding a tiny wood screw. Don't tighten
