I had a bunch of extra spools from eSun and generics that have the larger core diameter than Bambu spools. I wanted to reuse them on the VSpooler. After printing a few designs from MakerWorld and trying them, I decided that it might be better to be able to align the inside spool edge in the same location as when you are using a Bambu spool. The VSpooler tracks the filament all the way to this edge.

After spilling some gel beads while filling, I decided I needed a simple funnel!
