About this 3D model

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. Mk8 upgrade without cutting for REP 2 http://www.thingiverse.com/thing:35810 , adding oil to the filament as described at http://www.thingiverse.com/thing:103729 and Surface Finish Calibration Test Shape http://www.thingiverse.com/thing:39050 also helped greatly.
