About this 3D model

For those of you that like me didn't like what was out there to handle flexible filaments, this extruder designed for the CTC replicator dual it's a solid sturdier block that support the filament all the way to the hot end. (will allow you to adjust easily the high of your throat pipe) Printed with 40% infill, 4 top and bottom layers and 3 perimeters at 40 mm/s. Note: for those of you that will wonder how did I print outside the built plate...... Simplify3d (not cheap, but worth it) Sorry, I forgot to add the knob. just upload the new file with it. UPDATE 08/20/14: after several hours of printing with ABS, one of the arms broke. I would recommend printing the arms with 100% infill instead of 40% as I indicated before. UPDATE 02/18/15: After several months of using the design, I did some modifications. The new extruder works much better and cooling to the aluminum block was improved. (Print both main bodies at 70% infill, the bearing holders at 100% and fan cover at 20%) Note: You will have to modify the start G-code to prevent hitting the extruder against the frame of the printer.
