Simple PTFE guide

For Bambu Lab's filament I print from my AMS.Other brands i switch between the spool and straight from my (Polymaker) containers. with this solution it saved some hassle switching and without the need of a splitter. I used Steve Wagg's model for the connection part to the spool. thanks!
