tube catcher

i use 1.8 id ptfe to join filaments and i didn't want to cut anything to recover or remove it, so i threw together this thingie in orca slicer to hopefully catch and stop both that tube and the teflon ring that my sunlu drier uses for wear reduction.

not gonna promise it works, but it's an idea i'm playing with cuz it's simple.

edit: i've now used it through two spool changes and it's worked beautifully

i did have to use a drill and bore out the hole a little bit for smoothness, so that's a thing
