Filament Spool Flange for Auto Rewind Spool Holder

I made this flange to prevent my filament spools from traveling horizontally on the [spool holders](https://www.thingiverse.com/thing:3205383) I printed for my i3mk3 MMU2. They're slightly larger in diameter than the spool holder cylinder to allow for tape and any printing issues, I used duct tape to fine tune the friction fit so that they don't easily move.
