I print with the filament in the drier box which sits on top of my LACK enclosure and needed to turn the filament through 90 degrees in a way that doesn't add any friction. That's what this does. Gcode files are for a 0.4mm nozzle.

I've also included the guide cap and nut for the drier box. I converted mine to single spool so I needed another exit guide centrally placed. Converting to single spool allows for silica gel pouches to be placed on either side of the spool. The containers for which are listed separately.
