Compact extruder carriage

This is a compact extruder carriage designed for a sunhokey prusa i3 2015, but it probably fits other prusa i3 too.

The cooling fan is mounted on the back of the carriage. But the most unique thing about this design is that the extruder is clamped down at the bottom, fastening the extruder at two points.

It is made in openscad, but its very computer intensive and changing any of the parameters will likely break the design in non obvious ways, so i decided not to add it in the customizer.
