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.

Yes. I bought one of those cheap sunlu filament joiners (I think CNC Kitchen did a video on it?).

Basically, when a spool is at the point where I start caring how much filament is left on it? I put it off to the side. And two or three times a year I just listen to a podcast while I fuse all those spools (with the same material). Makes for some fun multicolor prints when one color ends and the next begins and basically means I have all the "infinite filament" benefits of a multi-filament system without costing hundreds of dollars.

I don't do much PETG but the sunlu has a setting for it (185C).
