Filament splicing? Do any of you guys do it? (sh.itjust.works)

I was getting rid of some spool ends the other day by manually feeding them in while printing. That way I was able to push all these ends past any sensors and into the extruder for uninterrupted printing. It came out fine but was quite tedious.

So this got me thinking: Do any of you guys splice filaments? Not only would this allow for more efficient material use, but I suspect a print made from a bunch of small segments of different colors could look kinda cool.

I'm primarily printing with PETG, so my question is specifically about that, but I'm sure the concept should work for other filaments too.

I've tried it a few different ways and the best outcome I've had was using some tubing, like this one: https://youtu.be/yuZ0DA8w9XI

I don't always do it but when I do, I do it this way from now on. The tube makes sure the filament stays aligned, I also cut the two ends at a 45 and try and join them up inside the tube. Usually I'll save the ends and then do a few rolls at once, can usually get another few prints out of it.
