Quick-Fit Support for Prusa i3

This is a support that allows quick change of extruder/hotend for prusa i3.
I updated the design to compact it, now the width is 80mm, so the gain is about 40 mm in X axe compared with the previous design.
I've deleted the previous stl files, but the FreeCAD file is still here (Quick-Fit-Extruder-Support.FCStd).
The new stl files are from Quick-Fit-Extruder-Support_v2.FCStd, so be carefull when you download the files.
