Filament Guide Pulley for Maketbot or Thing-O-Matic

thingiverse

This filament guide pulley allows me to put a CAT-6 box loaded with ABS filament on the floor, run the filament up and over the pulley, and down into the extruder. It is low friction, large diameter and has a deep slot to help guide the filament. Instructions !! YOU WILL NEED THE FULL 100mm x 100mm BUILD SURFACE !! If you have not replaced your build platform screws with flush head screws, this build is not for you. It will drive your extruder into the raised screw heads. Fair warning. See the attached image for an example full build platform. The thing is designed in OpenSCAD, and it is my first OpenSCAD design, so my apologies in advance for the code. The Filament_Pulley_SCAD_STL_0v0.zip includes: //The OpenSCAD design file Filament_Pulley_0v0.scad //High resolution STL of both parts of the holder, ready to Skeinforge Holder_Two_Halves_0v0.stl (print 1 copy) //High resolution STL of half the pulley, ready to Skeinforge Pulley_Half_0v0.stl (print 2 copies) The build instructions are annotated in the images.
