Anycubic Kobra Spool Collar

thingiverse

A simple friction fit collar to shorten the width of the open area on the Anycubic Kobra printers, so that your spool doesn't move all the way out to the side. I found that with the base wide spool holder, my smaller spools liked to "walk" all the way to the front edge of the holder, but with this clipped on, the 1kg spools still fit over without having to take the spool holder off and on, but keeps it to the back edge of the holder. A simple design to do something useful. Print as is, I'd suggest a minimal amount of fill so that you can still push it over the core of the spool without snapping it.
