Remixed: Spring loaded extruder for Leapfrog Creatr

My Leapfrog (received a month ago) had problems with filament tolerances I guess. During a print job, the filament was from time to time not transported and the nozzle clogged. Therefore I remixed the extruder from ROB65 http://www.thingiverse.com/thing:62468
I made the remix, because I wanted to use the original filament feeding. Now it works very well and the filament change is much easier.

For this extruder load the files and the instruction form ROB65 and replace the two idler-latch-V2
