Filament guide for Prusa i3 MK3S+ and Polymaker Polybox drybox Edition 2

Bought the Polymaker Polybox drybox Edition 2 to keep my filament dry. The box comes with some plastic tubing with a 6mm outer diameter to guide the filament to your printer but no way to mount it your printer. Searched a bit for already existing mounts/guides/adapters but none fitted out of the box my needs, so I remixed clivebradshaw his Filament Guide by adding a cylinder on it. So one end holds the tube which slides in tight, and the other end has a 2mm hole to let the filament exit the adapter. Print on its side with support on the bed for the protruded cylinder.
