I printed this and ran into an issue. When in slot 1 or slot 4 using a cardboard spool that was almost empty it had some issues spinning the spool. It would tug on the filament and lift the spool to the point that the spool would bump into the IFS and cause the filament to bind.
I tried sanding down the holder to make it a little smoother, but it didn't help.
A printer add-on that raises the IFS higher would likely solve this.
I highly recommend this version.
