Filament Guide Bar - no Restrictions

I wanted to provide a "guide" for the filament on my Anet A6 3D printer which prevented any restriction to the filament to minimize feeding issues.. I didn't want to use an "eyelet" type of guide, as it requires the spool to be in a specific location behind the printer (and I had other plans for that... forthcoming)

So I created a pair of brackets which mount to the top of the Anet A6 frame (pictured) through existing frame M3 screws. I ran a piece of aluminum (3/8" / 9.5mm) which I had around the house across the top... this allows the filament spool to be placed most anywhere, and allows complete freedom to the filament as the printer moves back and forth across the X axis. See pictures.

I've included the 123D file in case you need to modify the size of the hole for a different sized rod.
