This replaces the original ikea Lack filament guide entirely so that the original hole can be used for this remix and the filament feeding dry-box port referenced below.
Note: From my own experience and testing you may find that 4mm OD fittings and tube are better for short distances. longer lengths coupled with internal friction inside the tube create significant drag on the filament and your extruder may skip.
This should work best for any printer that uses a direct feed extruder. Printers that use a bowden system should work provided you load the filament into that system once it enters the enclosure (Although, you should optimize the location of this filament guide through the enclosure to make it easier to line up with your printers bowden feed).
