9. Spool Mount
9.1 Spool Mount Assembly
The spool mount can be used to mount a 1Kg reel of filament directly above the hot-end , with the filament feeding over
the top of the reel and giving a path of least resistance into the extruder. This arrangement minimises the drag on the
extruder from the filament.
Screw the M8 threaded bolt into one side of the PLA mount (with the close M8 hole), using a large pair of pliers, then
screw the second half on to the correct distance for your filament reel and mount on top of the frame (Fig 9.1a)
