Mount for 2020 Extrusion I-Type 5

Needed a mount for my filament spoolholder http://www.thingiverse.com/thing:1000323 and came up with this design.

Edit: 8. september 2015:
Added a mount based on the one without guide, with rounded top edges. Purely visual changes.

Added a mount without the middle and sideguides.
