I use a pringles can as a trash can for the prime lines, and was fed up of it taking up desk space so I just made a quick mount. I also have another one that has a cup that holds filament clips.
Diameter of the circle is 75.5mm.
The fit of the can is quite tight, so you may want to punch a hole in the bottom of the mount if you're having issues removing the can.
Don't try to spread the arms into the channels from the side. Go from the top and and just give them a gentle tug to get started, then slide the holder down the channel to your desired height.
No supports or brim requried, I did around 30% gyroid infill.
