This is a remix of http://www.thingiverse.com/thing:131656 to fit the bed of a Solidoodle 2 (rather than a Solidoodle 3). The Nozzle_cleaner.stl file included here is from the original thing, but has been flipped over. The cleaner.scad file is openscad that imports that stl, cuts it up, and joins it back together as a shorter piece that fits the Solidoodle 2.
This updated version includes two flavors. One that is plain (same as original) and one that has an M3 nut trap so a M3 bolt can be used to hold it in place more securely than wedging in pieces of paper.
Now, I've added a 3rd update with newcleaner.stl and newcleaner.scad. This is a complete redesign which will hopefully cling to the aluminum bracket better, and it provides multiple pipe cleaner loops since one sometimes didn't work.
