Customizable Spool Holder Base for Different Size Aluminum Extrusions

thingiverse

Update 11/3/2016 I added three new options to use this design with 1/2" EMT (Electrical Metal Tubing), 3/4" EMT or 1/2" PVC so that it can be used on an Emmett-Delta. This is a customizable base for the Universal stand-alone filament spool holder found at http://www.thingiverse.com/thing:508896 Since most of the work had already been done to make this design customizable for 2020 aluminum, I went further and made it customizable for six different extrusions by changing a few variables in the OpenSCAD script. By modifying these variables, users should be able to customize this design for many other sizes. There are two different profiles for the spool spindle shaft: original and new. These profiles are defined with the variable OriginalCenter set to 0 or 1. If you're using this design with original spindles, you'll want to set that to 0. I included test prints for Spool_Original_Spindle_And_Shaft_Test.stl & Spool_New_Spindle_And_Shaft_Test.stl so you can see how each version of the shaft fits the spindle without wasting a lot of plastic. I've only tested the 2020 version of this design, but I included test prints for aluminum 1515, 2020, 2525, 3030, 4020 or 4040 extrusions. Since there are so many possible combinations, I didn't include STL files for any of the final parts.
