Joining Filament

Why is there no tools for joining filament? I really hate the idea of changing filaments mid print. I need a tool for splicing filaments. Any ideas or links for tools…

It’s a difficult process to do well. There are a few fillament splicing rigs out there like this one https://www.thingiverse.com/thing:2600699 but generally you need to cut the fillament ends square, insert a heated flat surface (like a razor blade attached to a soldering iron) in between both ends, heat them up to melt point for whatever fillament you are using, squish them together, then trim the mushroomed out plastic around the splice well enough that the fillament won’t get hung up on the bore without removing enough material that it will break.

I’ve always wanted to put something together to do this…

Maybe weld short segment of 3mm metal tubing (split or sanded/ground/filed in half) on plier jaws. Ideally you would be able to join the filament. close and heat up the jaws with a soldering iron.
