Simple Printerbot LC Filament Guide
by dcartoon, published
This is a simple block + hole to help prevent misfeeds. It sits within the extruder body, just above the hobbed bolt.
Given the small hole for the filament, you will likely need to position your spool so that there's a relatively straight line between the spool and the filament guide. I have my spool positioned directly above my Printrbot.
