Extruder assistance
Guys, I’ m gonna need some help, and this community has been pretty good with that so far 
I’m making myself a Prusa i3 and the last few pieces i need to purchase are the cold end extruder. I’ve already bought the hobbed bolt that is for a wades extruder or greg’s hinged accessible. Sooo what i am after is the appropriate files for the Greg’s hinged accessible, as i have been notified that it was originally designed for the Mendel i2. I currently have these ones from Greg frost’s thingiverse http://www.thingiverse.com/thing:8252 but will that be able to fit onto the i3? If it won’t does anyone know the modified that can?
Cheers in advance
