Replicator (Dual) Filament Guide

thingiverse

Filament Guide for the Makerbot Replicator (Dual) The guide keeps the two filaments sufficiently away from the rear wall of the Replicator. The filaments are thus pulled up from the reels, instead of at an angle to prevent the filament from tangling betwen the reel and the wall. This is especially noticeable on the reel for the left extruder: the filament can become loose, and because of the "large" distance between the reel and the wall, it will roll between the reel and the wall, becoming a huge tangle. This guide was designed for the Replicator (Dual). It might work with a single extuder Replicator but a) I don't know if it's even necessary if the reel is close to the wall (like the right extruder reel in the Dual) and b) if it is indeed useful, it might not be as stable since it only attaches to one of the filament tubes. Version 2 of the Guide is a bit more robust, but otherwise it does the same and is printed the same way. Instructions Printing instructions You need to make sure that the first layer you print sticks well to the print bed, otherwise the bottom circular guides will come out looking badly. I printed this using ABS. 0.2 mm layers enable support ('doRaft' = true) Installation on the Replicator (Dual) The guide attaches to the filament tubes that are attached to the rear wall via the plastic clamps. Unclamp the two tubes. Slide the whole guide behind the thick power cable Slide the top circular guides onto the filament tubes from the top until they reach the bottom of the circular guides. They should fit snuggly. Re-attach the filament tubes to the rear wall with the clamps. Snap the filaments into the bottom circular guides though the vertical slits
