MakerFarm i3v Spool Holder Replacement

This design replaces the laser cut wood spool holder that comes with the MakerFarm 10" i3V 3D printer. I found the stock spool holder can require a far bit of inertia in order to rotate the filament spool which can cause under-extrusion. The new spool holder allows for much easier rotation of the filament spool.

The new design uses a 10mm wooden dowel to support the filament spool. A 20mm spacer is pressed onto the 10mm dowel to add more clearance between the spool and the bottom of the spool holder. The sides of the spool holder are fastened to the base using M3x25 screws.
