Dry Reel Holder

This reel holder design keeps your PLA dry.
PLA is very susceptible to moisture, it is essential that it is kept dry to prevent problems. http://www.shini.com/ep_edm/en/contect_246.html
The main problem I had was the extruder blocking, especially with older filament. Newly unpacked filament worked properly for a few hours but started blocking within a day.
Now I have been printing without problem for over a week.
