Wanhao Duplicator i3 Plus - Bearing spool holder

I wanted a spool holder for my Wanhao Duplicator i3 Plus that had bearings in it, so I made one. I designed the parts using a combination of Sketchup and 3D Builder. I've included the Sketchup file in case you want to modify something.

All you have to do is remove the supplied two-piece filament mount from the metal bracket. Then install this one in the hole in the existing bracket. The assembly should be pretty self-explanatory.
