maker farm prusa i3 8-10" modified extruder for ninjaflex 3mm

to popular request i modified the 3mm hole for 1.75 and uploaded new extruder, note i don't print 1.75 so i have no idea if this is going to work, if you print it in 1.75 and it works let me know, also if i can mod it to make it better let me know or just do it your self, I'm adding the google sketchup save file so any buddy can tweek its a free program for windows and mac
note sketchup will need stl plug in from extension ware house


print temp 225
bed 50
all speeds in slicer 30mm
