Prusa i3 Mk2 alternative Spool holder Frame Mount

This is an alternative spool holder that can be used on the Prusa i3 Mk2. If you plan on adding a cable chain to your Prusa i3 Mk2 you will not be able to use the standard Spool holder. A cable chain will rub into the bottom of the spool holder with taller prints. This version mounts to the top sides of the aluminum frame. You can use a 3/8 in Dowel rod as the rod for the spool.
