Slim filament guide for Prusa i2

I designed a filament guide for my Prusa 2, as none of the current designs felt quite right.

I wanted a design that can be installed without disassembling the printer, but does not have a slot for filament which might lead to filament getting stuck. I also wanted something that looks good and does not waste too much plastic.

It was designed in SolidWorks 2011 and repaired in Netfabb, so no SCAD files.
