O-ring replacement set for 1.75mm filament

Hygroscopic FDM filaments tend to absorb significant amounts of moisture from the environment over the course of a few days. Some materials cannot be printed out of the box due to high moisture levels already present in the material. The presence of moisture in filaments can cause visible artefacts during printing, including: poor surface finish, stringing and oozing. Moisture in filaments can potentially cause print failure and potentially affect the mechanical properties of the printed part. As a result moisture sensitive materials need to be dried prior to printing, however without special storage or pre -treatment the print quality can still degrade noticeably, especially during the course of a longer print
