Mini Delta Filament Holder

I had some roller blade wheel bearings lying around, so I designed as filament spool holder to fit over the existing filament arm. The bearings are a tight press-fit into the roller ends. The spool holders are a press fit onto the metal arm that comes with the printer.

I used Sketchup to create the parts, then Simplify3D to slice them. Printed them via the SD card as I cannot get Simplify3D to talk to the printer!@?!
