Filament Splicer

thingiverse

After printing and using trustfm's filament splicer joiner with moderate success, I decided to see if I couldn't improve on a splicer so that I could get consistent repeatable splices. Using mdkendall's Parallel Jaw Pliers as a base for the design, I modified the jaws to what you see here. Using the same procedures as in trustfm's joiner, I'm able to get consistent splices. After splicing, I remove the PTFE tube from the left jaw and then sand the joint so that it passes smoothly through the tube. To achieve a good splice, both ends of the filament being spliced need to be straightened so that the ends line up (and are parallel) with each other. I used M3 socket head cap screws throughout and a couple of screw caps from 3DPRINTINGWORLD. After hearing about GreenDot's issue with the fillet, I added a revised left side jaw.
