Lulzbot Mini Filament Mount
thingiverse
The Lulzbot Mini has a rectangular arm for holding the filament spool. The spool drags on the arm and causes a jerky motion of the spool. Others have designed spool holders for the Mini to alleviate this problem. Here is my version. The bolt is a ⅜ x 5” hex bolt. The Mounting bracket replaces the standard Mini arm. The cylinder is two parts glued together. The friction is very low, so the unit is very smooth in operation. The spool will even roll back when the head rises. The shoulder on the cylinder will fit through the holes of all the brands of filament I have tried, and requires no fastening or tightening of the cylinder to the filament spool. Everything is free floating. I used PLA.
