Have you ever run into the problem of running out of 3D printer filament mid-print? This can happen often with larger prints. Instead of having to figure out a way to feed a new spool into the feeder, if this can even be done, one man has come up with a new device for 59 euros. It's called FUSE, and it is basically a clamp which welds two different strands of 3D printer filament together. Whether during a print or prior to starting a print, it will give you peace of mind that you will not run out. More details on their Indiegogo campaign can be found here: http://3dprint.com/8845/fuse-3d-printer-filament/ Check out the short video clip below showing how the FUSE clamp works:
