"Frictionless" PLA spool holder
thingiverse
It's a remix of http://www.thingiverse.com/thing:128387 I have another Spool Holder and another Spools of PLA :) So, I created similar model in openJScad and print it. My rod has 16.5 mm diameter and spools are 38.2 mm diameter. Funny, but I had to print different sizes models for one spool. It's different on both sides.
