Replicator 2 Feed Tube Buddy
Trouble with the feed tube popping out and jacking up your print jobs? This may help.
Assemble A and B as shown in the photo. Print in makerware on defaults medium. Remove the feed tube and sand the small hole till the tube slides snugly through. Raise the ring to where the apex of your tube is when the extruder is at it's home axis. Insert the wiring bundle into the buddys lower ring access slot. Print stuff.
