Filament Coil Holder for Lulzbot Mini (remix)

The stock filament holder for the Lulzbot Mini is basically a printed stick and it works fine most of the time, but I did have the filament in a couple long overnight print jobs get jammed because the printer had to tug hard on the filament to overcome the friction between the spool and the stock coil holder. So I decided to replace it with something a little better.

I used the spool centers and knob without modification from this project: http://www.thingiverse.com/thing:219667 The skate
