Filament spool holder (25mm conduit) for the ORIGINAL PRUSA I3 MK2

This is a remix of StijnVanDamme's design http://www.thingiverse.com/thing:1794348
his design uses 20mm PVC conduit but 25mm electrical conduit is more common where I am from.
I remodeled the spool holders to press into the 21mm ID of the PVC pipe and modified the 2 arms for the 25mm OD.

This design is a big improvement over the original i3 spool holder!
