Multi-material feeder part, 4x-materials

thingiverse

I've been printing with this multi-material feeder part for a few months now, and the results have been incredibly successful. I'm very happy with how it's turned out. As you can see from the pictures, the prints are looking great. One thing to note is that the design is a bit taller than necessary - but that was a deliberate choice on my part. I wanted to keep the path angles as low as possible, which would help ensure smooth printing and minimal clogging issues. There are actually three different versions of this feeder part. They all require four M6 push fittings on top, but each version uses a slightly different configuration for securing the material. The first version has an M6 fitting at the bottom, while the second version uses an M10 fitting with a PTFE pass-through. The third version features a collet ring and lock, which also requires two M3 bolts and nuts to secure the collet in place. For making material changes, I use the filaswitch post-processor, which can be found on GitHub at https://github.com/spegelius/filaswitch. If you're interested in taking a closer look at the OpenSCAD source code for this design, it's available on GitHub as well - specifically in the 3DModels repository, under PrinterParts/Feeder4x.scad.
