Clip-on filament guide for Kossel Clear

This is a clip-on filament guide for the Kossel Clear or other printer based on 1515 extrusions. The openings are 6mm square going horizontally or vertically, about 6 x 3.5mm going diagonally. The smaller slot allows a cable tie to be put around the extrusion, in case the clip doesn't hold in place well enough on its own.
