This is a rework of DeAtHfOrToLd's http://www.thingiverse.com/thing:1505075. I have made the file into three separate parts to make it easier to print on the A8 bed for those that may have been having issues with warping of peeling.
I have also added a filament guide that is large enough to put some foam to clean the filament as it passed through.
The two spool carriages on either side are capable of full support of the roll without the center piece is you prefer to not use it.
This holder replaces the existing "spacers" on the LCD screen .
NOTE for printing you will need to rotate the parts so they lay flat on the print bed.
I chose to use supports for printing so the grove at the top for the supports doesn't deform but they are not required.
