Manual filament line changing device (material-saving version) PS: comes with pneumatic valve replacement

Because I don't have much money to buy a multi-color system, I saw others doing it quite well However, it was too time-consuming and used too much material So I thought I'd try to design one myself After printing it, I found it could also serve as a good alternative, so I published it Default settings are perfectly fine Even 166% ludicrous speed is okay, and it even prints faster The four screw holes are just for positioning the screws What kind of screws you use doesn't matter, as long as they can be screwed in to secure it

PTFE tube needs to be bought separately

Several lengths, cut to the appropriate length yourself
